The principles of Green Chemistry aim to improve the sustainability of chemical processes and reduce the generation of hazardous substances. There has been great growth in the field over the past few years and the number of research groups working in this area is still increasing. Now one of the biggest challenges is to embed the Green Chemistry ideals of safety and sustainability as standard, both in industry and academia. In order to do this, it is important to create resources that detail different applications and approaches.Green Synthetic Processes and Procedures brings together expert contributors from across a number of areas of green synthesis to cover a diverse array of subjects. Providing a thorough overview of the current green synthetic toolbox, from biocatalysis to sonochemistry, this book is a useful resource for any chemist wishing to design cleaner and safer processes.

The 20th century has seen a phenomenal growth in the global economy and continuous improvement in the standard of living in the industrialized countries. Sustainable development has become an ideal target in recent years and in the early 1990s the concept of "Green chemistry" was launched in the USA as a new paradigm, and since 1993 it has been promoted by the National Science Foundation (NSF) and the Environmental Protection Agency (EPA). The success of the pharmaceutical industry is, in large part, due to the towering achievement of organic chemistry, a mature science which emerged as a distinct discipline well over 150 years ago, however this has been both a blessing and a curse. Many of our most reliable strategies for assembling target molecules employ reactions which are fifty to one hundred years old and are often named in honour of their discoverers. During these early years, the chronic toxicological properties of chemicals were often completely unknown and many unwittingly became indispensable tools of the trade. Early pioneers in green chemistry included Trost (who developed the atom economy principle) and Sheldon (who developed the E-Factor). These measures were introduced to encourage the use of more sustainable chemistry and provide some benchmarking data to encourage scientists to aspire to more benign synthesis. Green chemistry is essentially the design of chemical processes and procedures that reduce or eliminate the use, or the generation, of hazardous substances. Green chemistry is a growing area of research and an increasing number of researchers are now involved in this field. The number of publications has dramatically increased and new recognition of advances made is necessary with respect to other research areas. The synthesis of "Fine Chemicals" represents one of the main goals in organic synthesis and this new book extensively examines the main processes and procedures for their preparation under eco-friendly conditions. The book is a collection of selected research topics delivered by scientists involved in some of the more prominent fields of green chemistry. It is devoted to the synthesis of fine chemicals by the use of alternative eco-friendly solvents (ionic liquids, polyethylene glycol, water, etc.), supported organic catalysis, microwave irradiation or high pressure as contributors to more efficient processes, photochemistry as a green procedure and solvent-free processes. Each chapter gives an introduction to the various methods or procedures and their contribution to green chemistry and a variety of the most representative examples of the eco-friendly synthesis of fine chemicals are reported and discussed. In addition, there is a chapter dedicated to the application of simple reaction to the synthesis of complex molecules.The chapters are all written by authors who are experts in their field and are exhaustively referenced and the book will be invaluable for researchers and industrialists as well as academia.

Discover a comprehensive exploration of recent progress in the preparation of nitroalkanes from two leading voices in the fieldNitroalkanes: Synthesis, Reactivity, and Applications delivers a thorough summary of the importance of nitroalkanes in organic synthesis. The book covers their preparation, transformation into other functional groups, like carbonyls and amines, and their use in the formation of single carbon-carbon or double carbon-carbon bonds. The distinguished authors have included chapters on acyclic and cyclic alpha-nitro ketones as well as the synthesis of cyclopropanes and spiro ketals.The book provides treatments of the application of nitroalkanes for the synthesis of important heterocycles, poly-functionalized structures, natural products, and compounds of biological and pharmaceutical interest. A one-stop resource in a topic that hasn???t been fully addressed by any other book in decades, this book covers the most important synthetic routes toward nitroalkanes.Readers will also benefit from the inclusion of: A thorough introduction to the synthesis of nitroalkanes, as well as the transformation of the nitro group into other functionalitiesAn exploration of the formation of C-C single bonds, C=C double bonds, and the breaking of C3C bonds from cyclic alpha-nitro ketonesDiscussions of acyclic alpha-nitro ketones, nitroalkanes as precursors of cyclopropanes, and the synthesis of spiro ketalsAn examination of the preparation and synthetic applications of 1,3-DinitroalkanesPerfect for organic chemists, natural products chemists, and catalytic chemists, Nitroalkanes: Synthesis, Reactivity, and Applications will also earn a place in the libraries of medicinal chemists seeking a one-stop resource for the most recent developments in the preparation of nitroalkanes, their functionalization, and their applications.
