Comprehensive Organic Synthesis


Book Description

The development of more effective routes to known materials and the production of new materials are important goals in many areas, including electronics, agriculture, medicine and textiles. Organic synthesis is central to achieving these goals. Comprehensive Organic Synthesisdraws together the common themes that underlie the many apparently disparate areas of organic chemistry which underpin synthetic strategies, thus providing a comprehensive overview of this important discipline. The contributions have been organized to reflect the way in which synthetic chemists approach a problem. In terms of organic molecules, the work is divided into formation of carbon-carbon bonds, introduction of heteroatoms and heteroatom interconversions. Thus, Volumes 1-5 focus on carbon-carbon formation, but also include aspects of heteroatom introduction. Volumes 6-8 concentrate on interconversion of heteroatoms, but also deal with exchange of carbon-carbon bonds for carbon-heteroatom bonds. Organization of the chapters is along the theme of selectivity, which is a critical question in determining the suitability of a synthetic method. Volume 9 contains cumulative author and subject indexes. Comprehensive Organic Synthesis will appeal to a wide audience. The set will be an essential reference work for all those seeking information on the solution of synthetic problems, whether they be experienced practitioners or chemists whose major interests lie outside organic synthesis. In addition, synthetic chemists requiring the essential facts in new areas, as well as students completely new to the field, will find Comprehensive Organic Synthesis an invaluable source, providing authoritative accounts of the essential facts and concepts.

Rules for the Nomenclature of Organic Chemistry


Book Description

Rules for the Nomenclature of Organic Chemistry: Section E: Stereochemistry (Recommendations 1974) deals with the main principles of stereochemistry. The rules discussed in this section have two main objects, namely, to prescribe, for basic views, terms that may provide a common language in all aspects of stereochemistry; and to define the ways in which these terms may be incorporated into the names of individual compounds. This book discusses the steric structure of a compound, which is denoted by an affix or affixes to the name that does not prescribe the stereochemistry. This text explains that isomers are termed stereoisomers when they differ only in the arrangement of the atoms in space. This book explains as well that the terms relative stereochemistry and relative configuration are used to describe the positions of substituents on different atoms in a molecule relative to one another. This book is a valuable resource for organic chemists.




Hypervalent Iodine in Organic Synthesis


Book Description

This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine.

Introduction to Nanoscience


Book Description

Nanoscience is not physics, chemistry, engineering or biology. It is all of them, and it is time for a text that integrates the disciplines. This is such a text, aimed at advanced undergraduates and beginning graduate students in the sciences. The consequences of smallness and quantum behaviour are well known and described Richard Feynman's visionary essay 'There's Plenty of Room at the Bottom' (which is reproduced in this book). Another, critical, but thus far neglected, aspect of nanoscience is the complexity of nanostructures. Hundreds, thousands or hundreds of thousands of atoms make up systems that are complex enough to show what is fashionably called 'emergent behaviour'. Quite new phenomena arise from rare configurations of the system. Examples are the Kramer's theory of reactions (Chapter 3), the Marcus theory of electron transfer (Chapter 8), and enzyme catalysis, molecular motors, and fluctuations in gene expression and splicing, all covered in the final Chapter on Nanobiology. The book is divided into three parts. Part I (The Basics) is a self-contained introduction to quantum mechanics, statistical mechanics and chemical kinetics, calling on no more than basic college calculus. A conceptual approach and an array of examples and conceptual problems will allow even those without the mathematical tools to grasp much of what is important. Part II (The Tools) covers microscopy, single molecule manipulation and measurement, nanofabrication and self-assembly. Part III (Applications) covers electrons in nanostructures, molecular electronics, nano-materials and nanobiology. Each chapter starts with a survey of the required basics, but ends by making contact with current research literature.
