Several B4CnH2n+4 compounds (n = 3;4, from 2butyne;5, from 1-pentyne) were synthesized from pentaborane and alkynes in the presence of 2,6dimethylpyridine. A mechanism study of the base catalyzed formation of B4CnH2n+4 compounds has led to the postulation of an abbreviated pathway. In the course of the mechanism study, apicaldeuteropentaborane was synthesized. Although a postulated intermediate B4H6.2,6-dimethylpyridine wasn't isolated, another B4H6-Lewis-base adduct, B4H7( - ) with boron trifluoride ethyl etherate yielded a small quantity of B4H10.

Boron Hydride Chemistry covers the significant contributions of boron hydride research in the subjects of bonding, structure, and stereochemistry. This book contains 12 chapters that illustrate the merging of certain areas of boron hydride chemistry with other disciplines, such as organic, organometallic, and transition metal chemistry. After providing an overview of the general geometric, stereochemical, and dynamic stereochemical features of boron hydrides, this book goes on exploring the bonding theory and theoretical research on boron hydrides, with an emphasis on boron hydrides that have open polyhedral structures. These topics are followed by discussions on gas phase and solution reactions of borane and substituted boranes. A chapter focuses on the chemistry of cations containing boron atoms bonded to hydrogen. The remaining chapters examine the syntheses, structures, bonding, spectral properties, and chemistry of specific boron hydrides, including borazines, closo-boron hydrides, carboranes, icosahedral carboranes, and close- and nido-heteroboranes. Inorganic chemists and researchers, teachers, and undergraduate inorganic chemistry students will find this book invaluable.

In this classic monograph, Nobel Prize–winning chemist William N. Lipscomb elucidates his area of expertise: the general structural principles and reactions of boron hydrides and related compounds. Lipscomb's work appeared only a decade after the structures of boron hydrides were first elucidated and their chemistry formulated into a widely applicable framework. His observations led to a major reconsideration of how atoms bond to form stable molecules. A concise treatment of the many separate parts of the structural theory and its relation to chemistry, this volume begins with an overview of boron hydrides and related structures, progressing to three-center bonds and their applications, molecular orbitals, nuclear magnetic resonance studies of boron hydrides and related compounds, and reactions of the boron hydrides. More than 120 diagrams and figures illustrate a variety of structures.

Platinum dibromide has been found to be a general dehydrodimerization catalyst for boron-boron linked polyhedral cage compounds. The reactions of a variety of small cage systems were explored, and all coupling reactions were found to proceed at moderate temperatures, were highly selective, and gave excellent yields of linked-cage products. These techniques have been used to prepare a number of new coupled cage boron hydrides and carboranes, including 1:1'-B4H92, 1:2'-B4H9B5H8, 1:2'-B4H91'-CH3B5H7, 1:2'-2-CH3B5H73'-CH3B5H7, and 2:2'-1,6-C2B4H52, as well as to provide synthetic routes to the previously known compounds, 1:2'-B5H82 and 2:2'-1,5-C2B3H42.

Base-Catalyzed Reactions of Hydrocarbons and Related Compounds focuses on the use of bases as catalysts for the conversion of hydrocarbons and related compounds. In order to emphasize the broad scope of base-catalyzed reactions, examples dealing with the conversion of non-hydrocarbons are given. Comprised of 14 chapters, this book begins with a historical overview of base-catalyzed conversions of hydrocarbons, followed by a discussion on the isomerization of olefins, acetylenes, and allenes, as well as the dimerization and oligomerization of hydrocarbons. The reader is then introduced to a variety of reactions, including those between aromatic hydrocarbons and olefins and between alkylpyridines and alkenylpyridines; homogeneous carbon-carbon addition reactions; and reactions of aprotic solvents with olefins. Subsequent chapters explore carbon-carbon addition of olefins with miscellaneous compounds; addition of ammonia, amines, and anilines to olefinic hydrocarbons; hydrogenation and oxygenation; dehydrogenation, aromatization, and hydrogen transfer; and dehydration of alcohols. This monograph will be of interest to chemists.
