Criteria of orbital symmetry conservation had a profound influence on mechanistic thinking in organic chemistry and are still commonly applied today. The author presents a coherent set of operational rules for the analysis of scope and reliability. It is written from the viewpoint of Orbital Correspondence Analysis in Maximum Symmetry (OCAMS). Its advantage lies in its provision of a coherent overview of the relation between symmetry and mechanism. For reasons of consistency, the book remains within the framework of molecular orbital theory.

Pericyclic Reactions,Volume 35-II covers the theoretical approaches to pericyclic reactions and reviews of pericyclic reactions of reactive intermediates and of particular reaction types. The book discusses some of the experimental approaches used to establish the authenticity of an apparent pericyclic reaction; the transient and observable carbocation rearrangements; and orbital symmetry interactions which are “extra stabilizing or destabilizing. The text then describes the pericyclic reactions of cumulenes; the cheletropic reactions; the applications of frontier molecular orbital theory to pericyclic reactions. A general theoretical model accommodating concerted reaction profiles for forbidden thermal reactions is also encompassed. Chemists and people involved in the study of pericyclic reactions will find the book invaluable.

A practical introduction to orbital interaction theory and its applications in modern organic chemistry Orbital interaction theory is a conceptual construct that lies at the very heart of modern organic chemistry. Comprising a comprehensive set of principles for explaining chemical reactivity, orbital interaction theory originates in a rigorous theory of electronic structure that also provides the basis for the powerful computational models and techniques with which chemists seek to describe and exploit the structures and thermodynamic and kinetic stabilities of molecules. Orbital Interaction Theory of Organic Chemistry, Second Edition introduces students to the fascinating world of organic chemistry at the mechanistic level with a thoroughly self-contained, well-integrated exposition of orbital interaction theory and its applications in modern organic chemistry. Professor Rauk reviews the concepts of symmetry and orbital theory, and explains reactivity in common functional groups and reactive intermediates in terms of orbital interaction theory. Aided by numerous examples and worked problems, he guides readers through basic chemistry concepts, such as acid and base strength, nucleophilicity, electrophilicity, and thermal stability (in terms of orbital interactions), and describes various computational models for describing those interactions. Updated and expanded, this latest edition of Orbital Interaction Theory of Organic Chemistry includes a completely new chapter on organometallics, increased coverage of density functional theory, many new application examples, and worked problems. The text is complemented by an interactive computer program that displays orbitals graphically and is available through a link to a Web site. Orbital Interaction Theory of Organic Chemistry, Second Edition is an excellent text for advanced-level undergraduate and graduate students in organic chemistry. It is also a valuable working resource for professional chemists seeking guidance on interpreting the quantitative data produced by modern computational chemists.

This well-illustrated book develops, using only the ideas of basic quantum chemistry (e.g. perturbation and symmetry theory), a fundamental conceptual and theoretical framework for chemical reactivity. By feeding the role of symmetry and chemical group topology directly into the development, the analysis generates and explains the successful features of simpler reactivity theories (e.g. frontier orbital theory, the isolobal concept, PMO theory, the Woodward-Hoffmann rules), as well as defines their limitations. The unifying construct is that of a group-resolved correlation diagram, which is shown to represent the formal quantization of the electron arrow, replacing the concept of classical point electrons moving between groups with the concept of quantum electron matter waves which evolve with the evolving nuclear and chemical group structure. The use of the concept of chemical groups (functional group system, substituents, solvents) is central to the development, localising the evolutionary electrons within the functional groups and leading to an isolation and analytic definition of substituent and solvent (catalytic) effects as explicit functions of the reaction coordinate. Each archetypical reaction family is represented by fully-worked examples: viz. aliphatic nucleophilic substitution, aromatic electrophilic substitution, inorganic rearrangements, electrocyclic additions, Diels-Alder additions and addition stages in chiral reactions.

The two-part, fifth edition of Advanced Organic Chemistry has been substantially revised and reorganized for greater clarity. The material has been updated to reflect advances in the field since the previous edition, especially in computational chemistry. Part A covers fundamental structural topics and basic mechanistic types. It can stand-alone; together, with Part B: Reaction and Synthesis, the two volumes provide a comprehensive foundation for the study in organic chemistry. Companion websites provide digital models for study of structure, reaction and selectivity for students and exercise solutions for instructors.

Orbital Symmetry: A Problem-Solving Approach was born of the necessity to present to students Woodward and Hoffmann's approach to pericyclic reactions. Hence the tone is introductory, and the book is addressed primarily to an audience of advanced undergraduate and beginning graduate students. The text seeks to familiarize the readers with several of the more often encountered methods of analyzing pericyclic reactions, and these methods should enable the analysis of virtually all of them. Problem solving is the foundation of the approach. Both the introductory and theory sections include problems to prepare the reader for the more extensive chapters of problems that follow. All problems (except those in Chapter VII) are answered in the text and are fully referenced where appropriate. Many of the problems require the use of molecular models if they are to be appreciated. Prentice-Hall's ""Framework Molecular Models"" and Benjamin's ""Maruzen Models"" are best suited for the construction of the highly strained molecules often encountered in the problems, and their use is recommended.

The steric and stereoelectronic effects control the rate and stereochemical outcome of reactions. Hence, a decent understanding of the related concepts is essential for successful synthetic planning. The book attempts to address several important issues related to these concepts in a simplified manner, and is intended for graduate students. It lays stress on the important aspects of steric and stereoelectronic effects and their control on the conformational profile and reactivity features. The book covers the geometrical requirements for reactions at saturated and unsaturated carbons in both cyclic and acyclic systems, and the resultant stereochemical features. The aspect of geometrical flexibility is also covered with a few examples involving intramolecular reactions. It deals with the facial selectivity of nucleophilic additions to acyclic and cyclic carbonyl compounds, and explains how the steric and stereoelectronic effects control the same. The work comments on allylic strains and their stereochemical control on different reactions with the related conformational control. It is a must read to understand the control elements, the prominent among these elements are spiro-conjugation, periselectivity, torquoselectivity, a-effect, Hammett’s substituent constants, Hammond postulate, and Curtin-Hammett principle.

Organic chemistry is constantly concerned with effecting reactions at a particular centre in a complex molecule, and if possible with a high and predictable level of stereoselectivity. In the light of much accumulated ex perience within organic chemistry it is usually possible to assess the likeli hood of alternative reaction pathways at least qualitatively. However, well based expectations can be falsified, and the experiments directed to the synthesis of vitamin B12 which led to Woodward's recognition of orbital symmetry control in organic chemistry are an instructive example. Our limi tations in this respect are very much accentuated in the case of hetero geneous reactions, which present additional problems, and except for very well studied instances, heterogeneous catalysis has remained a relatively empirical area of chemistry. Knowledge in this area has, however, been greatly improved by the development of transition metal complexes which replicate the catalytic properties of the metals, and are effective in a homo geneous reaction system. This development has advanced our understanding of catalysis by making it possible to interpret reactions in strictly molecular terms. In addition, these homogeneously active complexes are frequently more selective than their heterogeneous metallic counterparts either in discriminating between different functional centres in a molecule or in of fering better stereoselectivity. Homogeneous catalysts have now been devised for a number of organic chemical reactions, including hydrogenation, carbonylation, polymerisa tion, and isomerisation and dismutation of alkenes.
