REACTIONS OF PENTABORANE (9) AND PENTABORANE DERIVATIVES.

Abstract

A number of pentaborane derivatives are prepared in their (11)B and (1)H nmr spectra recorded and correlated. Assessments of alternative preparative schemes are given. An extension of the apex to base rearrangement reaction to polyalkyl pentaboranes reveals the following trends: The rate of rearrangement decreases with increasing number of alkyl substituents on the pentaborane framework; the rate increases with the use of stronger and less sterically hindered bases. Mechanistic inferences are discussed. (Author)
