Russell N. Grimes is Professor Emeritus of Chemistry at the University of Virginia, where he taught inorganic chemistry from 1963 to 2003 and mentored the research of 75 graduate students and postdoctoral associates as well as numerous undergraduates. He was a pioneer in the development of boron hydride and boron cluster chemistry and is author or co-author of over 240 peer-reviewed journal articles and review chapters. He has authored or edited four books, including 'Carboranes' (1970), 'Carboranes, Second Edition' (2011), 'Metal Interactions with Boron Clusters' (1982), and 'Inorganic Syntheses Volume 26' (1989), and wrote the chapter on Boron in 'Advanced Inorganic Chemistry, Sixth Edition' by Cotton, Wilkinson, Murillo, and Bochmann (1999). He is a native of Pennsylvania and earned a B.S. Chemistry degree at Lafayette College and a Ph.D. in Chemistry at the University of Minnesota, the research for which was conducted at Harvard University under the guidance of W N. Lipscomb followed by postdoctoral work under M. F. Hawthorne at the University of California at Riverside. He has been a Senior Fulbright Scholar at the University of Canterbury in New Zealand, a Humboldt Scholar and Guest Professor at Heidelberg University in Germany, and a Visiting Scholar at the Korea Advanced Institute for Science and Technology. He is a six-time American Chemical Society Tour Speaker and is a Fellow of the American Association for the Advancement of Science.
Carboranes, Second Edition is designed as a comprehensive source of information in a field that has experienced enormous growth in both its fundamental and applied aspects in the four decades since the publication of Carboranes (1970). During this long period thousands of original research papers have appeared, along with many review articles and book chapters dealing with aspects of carborane chemistry. As carborane science has grown in complexity, and applications have advanced steadily in areas such as medicine, nanostructured and electroactive materials, catalysis, polymers, and others, the need for a monograph covering the entire area in a unified treatment has become increasingly apparent.This volume has two principal objectives, the first of which is to provide a readable and concise introduction to the basic principles underlying the synthesis, structures, reactivity, and applications of carboranes and metallacarboranes at a level suitable for readers in industry and academe who are not trained in boron chemistry but find themselves working with, or lecturing about carboranes. Secondly, the book furnishes a trove of detailed information for workers active in carborane science and associated technologies. To that end, it incorporates tables listing thousands of specific compounds keyed to literature references, together with more than 2,000 molecular structure drawings that illuminate the accompanying discussion. Thorough treatment of the synthesis, structures, and reactions of carboranes, heterocarboranes, and metallacarboranes in the first 13 chapters is followed by four chapters detailing advances in practical applications in polymer science, catalysis, medicine, and other areas. - Includes over 2,000 molecular structure drawings throughout the text- Features tables listing thousands of compounds with key literature references
