The main subject division of this book include the theory of Diffuse reflectance spectroscopy; measurement and standardization of diffuse reflectance; instrumentation; application to color measurement and physical, inorganic, and organic chemistry; and applications in chromatographic analysis.While the use of reflectance spectroscopy dates from the 1920s, it has only been in the last decade that its analytical potential has been developed. Interestingly, much of the early research involved industrial uses where measurement of color was required. The development and acceptance of thin-layer chromatography has opened up new areas of analysis for the application of this technique.It is not the purpose of this book to delve deeply into the theoretical aspects of reflectance spectroscopy, as this book has already been done in several previous books. Insofar as it is possible, this book is an up-to-date guide to instruments and techniques intended primarily for the chemical analyst, though it is hoped that it may contain information of interest to other scientists. The potential for the application of this technique is great and the authors feel confident that the coming decade will see many interesting developments in this type of spectroscopy study, particularly in the field of analysis.

Much has been written about immobilized enzymes during this period of time. So much, in fact, that it can become difficult even for those involved in developing new enzymatic food processing operations to bridge the gap between the field of immobilized enzymes and their specific requirements. It is the purpose of this book to assist those engaged in this difficult task. It is also a goal to bring to the researcher in enzyme immobilization an appreciation for the requirements of the food processing industry.

To fully utilize Nuclear Magnetic Resonance (NMR) spectroscopy, a comprehensive and well-organized compilation of NMR data is necessary. While compilations have been available for other important NMR nuclei, such as carbon and fluorine, no comprehensive collection of data has been prepared for phosphorus-until now. The CRC Handbook of Phosphorus-31 Nuclear Magnetic Resonance Data provides a collection of 31P NMR chemical shifts for nearly 20,000 organic and inorganic phosphorus compounds. Each class of phosphorus compound is discussed. Bond types, stereochemistry (with the exception of metal complexes), media, important coupling constants, and data sources are included. The information is systematically organized according to coordination state, the atoms bound to phosphorus, and their connectivities. A comprehensive series of bar charts is also included to allow structure types to be assigned to chemical shift data. This handbook is an invaluable resource for all scientists working with phosphorus compounds, including chemists, biochemists, medical researchers, and pharmaceutical chemists.

Piperidine-Based Drug Discovery outlines the complexities of Piperidine scaffold use in drug discovery, including derivative chemistry, structural properties, methods of synthesis and practical implementations. Piperidine scaffolds are the cornerstones of over 70 commercialized drugs (including multiple blockbusters). Designed as a guide for both experts and students working in this and related areas, it is hoped that this volume will encourage and inspire the continued design and development of novel pharmaceuticals based on Piperidine and its derivatives. Heterocyclic compounds are of central importance to medicinal chemistry, as demonstrated by the high percentage of marketable drugs that feature heterocyclic fragments in their structures. As starting points for drug discovery they offer a broad range of attractive properties, and a detailed understanding of the particular characteristics of each is of great benefit to researchers. The most commonly used heterocycle among US FDA approved pharmaceuticals, Piperidine is an extremely important building block in the synthesis of medicinal agents. This heterocycle and its derivatives exhibit a number of important functionalities and have been employed variously as CNS modulators, antiaggregants, anticoagulants, antihistamines, anti-cancer drugs and analgesics.

Used in the production of a wide number of fine chemicals and pharmaceuticals, the Friedel-Crafts acylation reaction represents a synthetic process of great interest to organic chemists of academia and industry. Nearly 40 years since the last major treatise on the topic and reflecting the growing emphasis on green technology, Advances in Friedel-Crafts Acylation Reactions: Catalytic and Green Processes focuses on how to make this reaction more economically and environmentally friendly by using green acylating conditions, thus minimizing the formation of waste and decreasing production costs. Divided into four parts, the book explores stoichiometric acylations, catalytic homogeneous acylations, catalytic heterogeneous acylations, and phenol acylations. It is structured according to the role played by the catalyst in the activation of reagents as well as in the different modes of regioselectivity encountered in the acylation of arenes, aromatic ethers, and phenols. Incorporating examples of all acid-catalyzed Friedel-Crafts acylation reactions, the text considers classic Lewis and Broensted acid types along with more innovative and advanced multicomponent superacid catalysts. These range from rare earth triflates or triflimides and their combination with ionic liquids to metal-promoted zeolites and zeotypes, clays, polymetal oxides, sulfated zirconia, heteropoly acids, and Nafion. The book emphasizes the major industrial applications, providing a critical assessment of the differences, advantages, and disadvantages of homogeneous and heterogeneous catalysis. Helping readers to better understand the mechanism of the Friedel-Crafts acylation, the examples in the book substantiate the development of more effective catalysts and more selective processes achieved during the last few decades, enabling industry to embark on a safer and more efficient synthesis of aromatic ketones for the manufacture of a wide array of products.

The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer for all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.
