Some chemistry of hindered organoboranes

Abstract

Boron stabilised carbanions can be made through the use of highly hindered diarylboranes. Some reactions of the anions so produced are discussed. A spin-off of this work is the production of some stable mono and diarylboranes which hold great promise as reagents of general application. In a similar fashion, highly hindered and very stable aikyldiarylhydroborates are now available for selective reductions. It is clear that hindered organoboranes offer a wide variety of new reagents and reactions to enlarge both the theory and practise of organic chemistry. © 1994 IUPAC
