This book provides a comprehensive, step-by-step approach to organic process research and development in the pharmaceutical, fine
chemical, and agricultural chemical industries. Process R&D describes the steps taken, following synthesis and evaluation, to bring key
compounds to market in a cost-effective manner. More people are being hired for work in this area as increasing numbers of drug candidates are
identified through combinatorial chemistry and high-throughput screening. The book is directed to industrial (primarily organic) chemists, and
academicians (particularly those involved in a growing number of start-up companies) and students who need insight into industrial process R&D. Current books do not describe hands-on, step-by-step, approaches to solving process development problems, including route, reagent,
and solvent selection; optimising catalytic reactions; chiral syntheses; and "green chemistry." "Practical Process Research and Development" will be a valuable resource for researchers, managers, and graduate students.
* Provides insights into generating rugged, practical, cost-effective processes for the chemical preparation of "small molecules"
* Breaks down process optimization into route, reagent and solvent selection, development of reaction conditions, workup, crystallizations and more
* Includes over 100 tips for rapid process development
* Presents guidelines for implementing and troubleshooting processes

Chemistry is considered to be one of the prime causes of environmental pollution and degradation. The United Nations General Assembly also addressed the environmental challenges in its Sustainable Development Goals (SDGs), which have been adopted in 2015. A closer look shows that to meet these goals chemistry will play an important role. Green chemistry encompasses design and synthesis of environmentally benign chemical processes, green approaches to minimize and/or remediate environmental pollution, the development of biomaterials, biofuel, and bioenergy production, biocatalysis, and policies and ethics in green chemistry. When products in use today become waste, we need to treat that waste so that hazardous substances are not re-circulated into new products. In this context, circular economy is also an important point of discussion, which focuses on recycling, reuse and use of renewable sources. The theme of the International Conference on "Green Chemistry in Environmental Sustainability & Chemical Education (ICGC-2016) held in Delhi from 17-18 November 2016 was to discuss the emerging green trends in the direction of sustainability and environmental safety. ICGC-2016 consisted of keynote, plenary and invited lectures, panel discussion, contributed oral papers and poster presentations. The conference provided a platform for high school students, undergraduate and postgraduate students, teaching fraternity and young researchers to interact with eminent scientists and academicians from all over the world who shared their valuable views, experience and research on the harmonious methods in chemistry for a sustainable environment. This volume of proceedings from the conference provides an opportunity for readers to engage with a selection of refereed papers that were presented during the ICGC-2016 conference. The overarching goal of this book is to discuss most recent innovations and concerns in green chemistry as well as practical challenges encountered and solutions adopted to remediate a scathed environment into a pristine one. It includes an extensive variety of contributions from participants of ICGC-2016 that demonstrate the importance of multidisciplinary and interdisciplinary approach to problem solving within green chemistry and environmental management. The proceedings is thus a green chemistry monograph resulting from the fruitful deliberations in the conference, which will deeply enhance awareness about our responsibility towards the environment.

Considering the challenge of sustainability facing our society in the coming decades, catalysis is without any doubt a research area of major importance. In this regard, asymmetric organocatalysis, now considered a pillar of green chemistry, deserves particular attention. The first chapter of this volume examines the topic of asymmetric organocatalysis in light of radical chemistry. Recent important progress in this field has been attained by promoting the formation and harnessing the high reactivity of open-shell intermediates. Merging organocatalysis with radical chemistry has been the key to solving some longstanding bottlenecks, and has also significantly contributed to reinforcing the key role of organocatalysis in asymmetric catalysis. This chapter presents the most significant developments in this area, with a particular focus on asymmetric SOMO- and photoredox-organocatalyzed transformations. Chapter 2 focuses on quaternary ammonium salts (R4N+X-), especially chiral derivatives, and their behavior as unique catalysts in organocatalysis. Forming chiral ion-pairs capable of promoting asymmetric reactions, they also operate as unique "transporters" involved in phase transfer catalytic processes between liquid-liquid or liquid-solid systems. Furthermore, they offer unique opportunities when forming cooperative ion-paired entities R4N+X-, allowing a synergistic implication of the counter-ion X- either as Bronsted bases or Lewis bases. Specific design of such chiral catalysts in modern chemistry and better insight into their mode of activation facilitates efficient and unprecedented chemical transformations. This chapter provides an overview of the use of chiral quaternary ammonium salts in organocatalysis, emphasizing both general mechanistic aspects and the scope of this approach.

The origin of life is one of the biggest unsolved scientific questions. This book deals with the formation and first steps of the chemical evolution of nucleic acids, including the chemical roots behind the origin of their components from the simplest sources in a geochemical context. Chemical evolution encompasses the chemical processes and interactions conducive to self-assembly and supramolecular organization, leading to an increase of complexity and the emergence of life. The book starts with a personal account of the pioneering work of Stanley Miller and Jeffrey Bada on the Chemistry of Origins of Life and how the development of organic chemistry beginning in the 19th century led to the emergence of the field of prebiotic chemistry, situated at the frontier between organic, geo- and biochemistry. It then continues reviewing in tutorial manner current central topics regarding the organization of nucleic acids: the origin of nucleobases and nucleosides, their phosphorylation and polymerization and ultimately, their self-assembly and supramolecular organization at the inception of life.

The accurate interpretation of infrared spectra of organic structures is an extremely important tool for the analytical chemist. Using up-to-date source material, this volume presents a compilation of the infrared absorption regions of ninety of the most important organic molecular fragments. This highly practical guide introduces the reader to a straightforward technique for determining all the fundamental vibrations of a molecular fragment. The set of normal vibrations and the infrared absorption regions of ninety molecular fragments are then discussed and tabulated. The discussion of each fragment is accompanied by a large number of references. A Guide to the Complete Interpretation of Infrared Spectra of Organic Structures offers the analytical chemist the possibility of a more profound interpretation of infrared spectra. In addition, it assumes only a basic knowledge of infrared spectra, and so will prove very useful for non-specialists who use infrared spectroscopy in analysis.
