of improved catalysts, and their application in organic synthesis,
biocatalysis, and supported organometallic catalysis. As a result,
readers will gain a deeper understanding of the catalytic
transformations, allowing them to adapt the knowledge to their own
investigations.
Carola Vogel's PhD thesis focuses on the synthesis, and structural and spectroscopic characterization of the first high valent iron nitride complexes. In her interdisciplinary and collaborative research Carola also describes the reactivity studies of a unique iron (V) nitride complex with water. These studies show that quantitative yields of ammonia are given at ambient conditions. High valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.
Heterogeneous catalysis and mathematical modeling are essential components of the continuing search for better utilization of raw materials and energy, with reduced impact on the environment. Numerical modeling of chemical systems has progressed rapidly due to increases in computer power, and is used extensively for analysis, design and development of catalytic reactors and processes. This book presents reviews of the state-of-the-art in modeling of heterogeneous catalytic reactors and processes.
Catalysis plays a vital role in chemical, petroleum, agriculture, polymer, electronics, pharmaceutical, and other industries. Over 90 percent of chemicals originate from catalytic processes. Toughening economic and environmental constraints have proven to be a challenge for meeting the demand of novel efficient and sustainable regio- and stereoselective catalyst systems. Environmentally Sustainable Catalytic Asymmetric Oxidations provides a comprehensive overview of existing ecologically friendly catalyst systems for various asymmetric oxidation processes. Topics include: A survey of existing transition metal-based catalyst systems for asymmetric epoxidations (AEs) with O2 and H2O2 Asymmetric sulfoxidations with H2O2 on chiral metal complexes An overview of various transition metal-catalyzed oxidative transformations with H2O2 or O2 used as the terminal oxidant Organocatalytic asymmetric oxidations Catalytic processes of stereospecific oxidations of C-H functional groups The role that oxoiron(V) intermediates play in chemo- and stereoselective oxidations catalyzed by non-heme iron complexes The book concludes with a discussion of the opportunities and problems associated with the industrial application of stereoselective processes of catalytic oxidation with H2O2 and O2. It also provides examples of processes with industrial potential. Some of the catalysts presented in this book may serve as promising alternatives for existing catalysts-progressively replacing them in manufacturing processes and ultimately making the chemical industry greener and cleaner.

In this book the authors describe how they reproduced the redox functions of biocatalysts artificially. It includes the introduction and discussion of synthetic reactions via electron transfer, hybrid -conjugated systems, and biorganometallic conjugates as novel redox systems. The work was conducted in pioneering fields based on redox systems, in synthetic organic chemistry, synthetic materials chemistry, and bioorganometallic chemistry. The step-by-step process is illustrated by the three major parts of the book: redox reactions (selective synthetic methods using metal-induced redox reactions), redox systems (design and redox function of conjugated complexes with polyanilines or quinonediimines and molecular bowl sumanene), and design of bioorganometallic conjugates to induce chirality-organized structures (bio-related structurally controlled systems). This systematic and up-to-date description will be of special interest to graduate students who are meeting the new challenges of chemistry, as well as to post-doctoral researchers and other practicing chemists in both academic and industrial settings.
The author has developed novel methodologies for highly efficient construction of functionalized heterocycles by palladium-catalyzed domino/cascade cyclization of allenes and related compounds containing appropriate nucleophilic group(s). Based on these methodologies, enantioselective total syntheses of bioactive natural products, pachastrissamine (26% overall yield in seven steps), lysergic acid (4.0% overall yield in fifteen steps), lysergol (3.6% overall yield in fifteen steps) and isolysergol (8.2% overall yield in eleven steps) have been achieved. These are more facile synthetic route than those previously reported. These findings would contribute to the development of efficient synthetic methods for biologically active compounds containing a complex structure.

Heterogeneous Photocatalysis: Relationships with Heterogeneous Catalysis and Perspectives highlights the differences between thermal-catalysis and photo-catalysis and indicates borderlines, in particular, the possible synergism between them. The book outlines the basic aspect of thermal- and photo-catalysis, along with the most important characterization techniques. In addition, it presents case studies of thermal-catalytic and photo-catalytic or thermal-photo-catalytic reactions and includes a comparison between the results obtained using an inorganic solid as thermal catalyst and photocatalyst for the same reaction, and in the same setup. Final sections offer information on the preparation methods of (photo)catalysts, various techniques used for their characterization, engineering and economical aspects. This book will be a valuable reference source for students and researchers involved in heterogeneous photocatalysis and catalysis, chemistry, chemical engineering, materials science, materials engineering, environment engineering, nanotechnology and green chemistry.
Written for senior undergraduate and graduate students, as well as those chemists unfamiliar with "frustrated Lewis pairs (FLPs)", this text serves as an introduction to the both the concept and application of FLPs in hydrogenation catalysis. The book begins by setting the stage as it was around the turn of the century. While the dramatic impacts of catalysis were undeniable, there was dependence of such technologies on transition metal chemistry. Contrastingly, the chemistry of main group elements was dominated by Lewis acid-base behavior. However, these perceptions were altered with the discovery of the ability of "frustrated Lewis pairs (FLPs)" to activate dihydrogen. The basic features, and mechanisms of action of these unique main group systems are chronicled, while the evolution of the initial findings to applications in catalytic hydrogenation is discussed. A subsequent chapter focuses on the breadth of organic substrates for which borane based FLP hydrogenations are effective. This is furthered with a chapter on the metal-free enantioselective reductions. FLP chemistry is not limited to systems involving boranes and this book also catalogues a range of FLP hydrogenation catalysts involving elements from across the periodic table. The final chapter in the book describes other directions of interest where the application of the concept of FLPs hydrogenation are beginning to emerge. Ideal for course use and self study, this book provides synthetic chemists with a fresh, expert introduction to the field. The reader will be left recognizing that hydrogenation catalysts is a domain no longer limited to transition metals.
Micelles are prevalent in naturally occurring and biological catalytic reactions. However, it is only in recent decades that scientists have developed kinetic models clarifying how micelle-mediated catalysis works at a molecular level. Written by a leading expert in the field, Micellar Catalysis is an in-depth examination of how micelles affect reaction mechanisms and reaction rates in organic and inorganic reactions. The book first discusses the structural and chemical properties of micelles and the role of thermodynamics, concentration, and additives in forming micelles. Demonstrating how intermolecular forces influence the reaction mechanisms, the author presents kinetic models for reactions catalyzed by normal micelles, as well as mixed micelles and metallomicelles. The book also compares various types of catalytic reactions with and without micelles to quantify their effect on reaction rates and rate constants. Using this information, it illustrates how micelles can modify reaction rates and improve catalytic efficiency, particularly for industrial processes. The final chapter explains the principles of kinetics used for data analysis. Focused on kinetic, chemical, and physical aspects of micelle-mediated reactions, this book offers clear insight into the complex mechanisms that occur in biological reactions. Micellar Catalysis is an essential source of reference for scientists involved in the research and development of micelles for industrial and biochemical applications.

The Nobel Prize in Chemistry 2007 awarded to Gerhard Ertl for his groundbreaking studies in surface chemistry highlighted the importance of heterogeneous catalysis not only for modern chemical industry but also for environmental protection. Heterogeneous catalysis is seen as one of the key technologies which could solve the challenges associated with the increasing diversification of raw materials and energy sources. It is the decisive step in most chemical industry processes, a major method of reducing pollutant emissions from mobile sources and is present in fuel cells to produce electricity. The increasing power of computers over the last decades has led to modeling and numerical simulation becoming valuable tools in heterogeneous catalysis. This book covers many aspects, from the state-of-the-art in modeling and simulations of heterogeneous catalytic reactions on a molecular level to heterogeneous catalytic reactions from an engineering perspective. This first book on the topic conveys expert knowledge from surface science to both chemists and engineers interested in heterogeneous catalysis. The well-known and international authors comprehensively present many aspects of the wide bridge between surface science and catalytic technologies, including DFT calculations, reaction dynamics on surfaces, Monte Carlo simulations, heterogeneous reaction rates, reactions in porous media, electro-catalytic reactions, technical reactors, and perspectives of chemical and automobile industry on modeling heterogeneous catalysis. The result is a one-stop reference for theoretical and physical chemists, catalysis researchers, materials scientists, chemical engineers, and chemists in industry who would like to broaden their horizon and get a substantial overview on the different aspects of modeling and simulation of heterogeneous catalytic reactions.

This text explains how to apply concepts in chemical reaction engineering and transport phenomena to the design of catalytic combustion systems. It features three examples where catalytic combustion is utilized as a primary combustion process and natural gas is used as a fuel for stationary gas turbines, process fluid heaters and radiant heaters. These examples cover much of the area where research is currently most active. In each of these there are environmental benefits to be gained illustrating catalytic combustion as a cleaner primary combustion process. The dominant heat transfer processes in each of the applications are different, as are the support systems, flow geometrics and operating conditions. This provides a framework for the modelling and experimental techniques described in this book, offering the reader the opportunity to gain a broader knowledge base and develop the skills of problem solving and system modelling.
This book is indexed in Chemical Abstracts Service 'The present book displays the continuing broad interest in the area of Supramolecular Catalysis. It provides an excellent update to previous contributions in the field and will be highly beneficial reading for all students and researchers interested in the challenges faced in this domain of Supramolecular Chemistry.'Jean-Marie LehnNobel Laureate The construction of catalysts by supramolecular forces has recently become a powerful tool and the role of noncovalent interactions can assist in designing new tools for the construction of effective and selective catalytic systems. It is unquestionably, vastly important to understand how different noncovalent interactions can be controlled or manipulated under appropriate reaction conditions. Supramolecular catalysts have had a tremendous impact on the syntheses of both chemical commodities and fine chemicals over the last 50 years, leading to the discovery of new reactions that were previously deemed impossible. This means that supramolecular chemistry plays a predominant role in accelerating or understanding chemical reactions.This book which addresses the above points is written by some of the leading contributors in this field and is intended for graduate students, researchers and academics working in supramolecular chemistry, organic chemistry, inorganic chemistry, and physical chemistry as well as researchers with an interest in the area of catalysis. The authors give examples illustrating the growth of the field, especially with special emphasis on new results published over the last decade. They also provide an explanation of fundamentals and topical research. |
