BASE CATALYZED REACTIONS OF BORON HYDRIDES

Abstract

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.
