The chemistry of superacids has developed in the last two decades into a field of growing interest and importance. Now available in a new expanded second edition, this definitive work on superacids offers a comprehensive review of superacids and discusses the development of new superacid systems and applications of superacids in the promotion of unusual reactions. Covering Bronsted and Leurs superacids, solid superacids, carbocations, heterocations, and catalyzed reactions, this timely volume is invaluable to professionals, faculty, and graduate students in organic, inorganic, and physical chemistry. The chemistry of superacids deals with acid systems stronger than conventional strong mineral Bronsted acids such as sulfuric acid and Lewis acids such as aluminum trichloride. The first edition of Superacid Chemistry, published in 1985, quickly became the definitive work in the field. Since that time, however, the field has grown exponentially, with the development of new superacid systems and innovative superacid applications. This Second Edition of Superacid Chemistry has been published to bring this acclaimed book fully up to date with all these new developments. Superacid Chemistry features a team of pioneering authors in the field headed by George Olah, the 1994 Nobel Laureate in Chemistry. The book covers: * General aspects of superacid chemistry, including types of superacids and experimental techniques for acidity measurements * Superacids systems, including primary, ternary, and solid superacids * Carbocations in superacids, including methods of generating carbocations in superacids and methods and techniques in the study of carbocations * Heterocations in superacids, including onium ions, enium ions, homo-, and heteropolyatomic cations, and cations of group 6-12 elements * Superacids catalyzed reactions, including conversion of saturated hydrocarbons and alkylation of aromatic hydrocarbons Extensive references are provided throughout the book to guide readers to the primary literature for further in-depth investigations. In short, this Second Edition meets the growing need for current information on superacid chemistry among researchers in inorganic, organic, and physical chemistry in order to support and advance their research.
