The Borane, Carborane and Carbocation Continuum

Alles ber Carbokationen, Borane und Carborane - leichtgewichtige Elektronenmangelverbindungen, die einerseits immer mehr Anwendungen finden und die sich andererseits durch Fortschritte der Rechenmethodik theoretisch immer besser beschreiben lassen. Unter den erfahrenen Autoren sind auch zwei Nobelpreistrger, William Lipscomb und George Olah. (06/98) JOSEPH CASANOVA, PhD, is Professor of Chemistry Emeritus at the California State University, Los Angeles, and a senior research fellow of the Loker Hydrocarbon Research Institute, University of Southern California.
