Book Description
This book is about compounds such as the boron hydrides and associated metal hydrides and alkyls which acquired the label 'electron deficient' when they were thought to contain too few valence electrons to hold together. Though they are now recognized as containing the numbers of bonding electrons appropriate for their structures, the term 'electron deficient' is still commonly applied to many substances that contain too few valence electrons to provide a pair for every pair of atoms close enough to be regarded as covalently bonded. The study of such substances has contributed much to chemistry. Techniques for the vacuum manipulation of volatile substances were devised specifically for their study; developments in valence theory resulted from considerations of their bonding; and the reactivity of several (for example, diborane and complex metal hydrides, lithium and aluminium alkyls) has made them valuable reagents. The purpose of this book is to provide an introduction to the chemistry of these fascinating compounds. The experimental and spectroscopic methods by which they can be studied are outlined, the various types of structure they adopt are described and profusely illustrated, and the relative merits of extended valence bond and simple molecular orbital treatments of their bonding are discussed, with as liberal use of diagrams and as limited recourse to the Greek alphabet as possible. A recurring theme is the importance attached to considerations of molecular sym metry. Their reactions are treated in sufficient detail to show whether these reflect any deficiency of electrons.

Book Description
Nucleophilic aromatic substitution in carbo- and heteroaromatic systems is a subject of considerable interest to chemists. This book uniquely addresses the systematic analysis of a vast range of nucleophilic substitutions of aromatic hydrogen. - Nucleophilic displacement of hydrogen (the S N/H reactions) in pi-deficient aromatics, such as nitroarenes, arene-metal complexes, and the like - Nucleophilic displacement of hydrogen in heterocyclic substrates such as pyridines, their aza and benzo analogs, pyrylium and thiapyrylium cations, and other heterocycles - Mechanisms for the S N/H reactions (S N/H(AE), vicarious nucleophilic substitutions, and radical S N/H substitutions

Book Description
This first comprehensive overview of the rapidly growing field emphasizes the use of hydrogen bonding as a tool for organic synthesis, especially catalysis. As such, it covers such topics as enzyme chemistry, organocatalysis and total synthesis, all unified by the unique advantages of hydrogen bonding in the construction of complex molecules from simple precursors. Providing everything you need to know, this is a definite must for every synthetic chemist in academia and industry.

Book Description
Selectivity is an increasingly important part of organic synthesis. The whole basis of organic chemistry, and especially organic synthesis, depends upon the selectivity which can be achieved in organic reactions. This concise textbook describes the strategies which can be adopted to improve selectivity, and the reactions which have been specially designed to afford high selectivity. The aim is to illustrate the range of processes to which these principles can be applied and the high degree of selectivity which can be achieved. Selectivity in Organic Synthesis aims to provide a solid introduction to this subject, focusing on the key areas and applications.
