Hard and Soft Acids and Bases Principle in Organic Chemistry deals with various phenomena in organic chemistry that are directly related to or derived from the hard and soft acids and bases (HSAB) principle. Topics covered range from chemical reactivity to displacement reactions, along with various HSAB principle applications. This text consists of 11 chapters and begins with a historical overview of the HSAB concept, followed by a classification of hard and soft acids and bases and their theoretical descriptions. The reader is methodically introduced to the stability of organic compounds and complexes; displacement reactions of HSAB; and the chemistry of alkenes, aromatic, and heterocyclic compounds. The reactivity of organophosphorus and carbonyl compounds; organosulfur compounds and other chalcogenides; and organoboranes is also considered. The book concludes with an evaluation of other applications of the HSAB principle, paying particular attention to solubility and protonation; carbenes and nitrenes; the organic chemistry of group IV elements; and the reactions of organohalides, Grignard, and related agents. This book is intended for senior undergraduates or graduate chemistry majors, as well as organic chemists who are not familiar with the HSAB concept.

Presents both the fundamental concepts and the most recent applications in solid-phase organic synthesis With its emphasis on basic concepts, Solid-Phase Organic Synthesis guides readers through all the steps needed to design and perform successful solid-phase organic syntheses. The authors focus on the fundamentals of heterogeneous supports in the synthesis of organic molecules, explaining the use of a solid material to facilitate organic synthesis. This comprehensive text not only presents the fundamentals, but also reviews the most recent research findings and applications, offering readers everything needed to conduct their own state-of-the-art science experiments. Featuring chapters written by leading researchers in the field, Solid-Phase Organic Synthesis is divided into two parts: Part One, Concepts and Strategies, discusses the linker groups used to attach the synthesis substrate to the solid support, colorimetric tests to identify the presence of functional groups, combinatorial synthesis, and diversity-oriented synthesis. Readers will discover how solid-phase synthesis is currently used to facilitate the discovery of new molecular functionality. The final chapter discusses how using a support can change or increase reaction selectivity. Part Two, Applications, presents examples of the solid-phase synthesis of various classes of organic molecules. Chapters explore general asymmetric synthesis on a support, strategies for heterocyclic synthesis, and synthesis of radioactive organic molecules, dyes, dendrimers, and oligosaccharides. Each chapter ends with a set of conclusions that underscore the key concepts and methods. References in each chapter enable readers to investigate any topic in greater depth. With its presentation of basic concepts as well as recent findings and applications, Solid-Phase Organic Synthesis is the ideal starting point for students and researchers in organic, medicinal, and combinatorial chemistry who want to take full advantage of current solid-phase synthesis techniques.
