STUDIES ON 2,3-DICARBAHEXABORANE (8) AND RELATED COMPOUNDS.

Abstract

The reaction between alkynes and pentaborane at elevated temperatures was studied. Increasing the number of alkyl groups about the triple bond of the alkyne enhanced the reactivity toward pentaborane and resulted in increased yields of the corresponding 2,3-dicarbahexaborane(8). Attempts to effect a direct conversion of alkynes and pentaborane to the appropriate 2,4-dicarbaclovoheptaborane(7) were unsuccessful. The decomposition of 2,3-dicarbahexaborane(8) in a silent electric discharge apparatus gave improved yields of 1,5-dicarbaclovopentaborane(5) and 1,2-dicarbaclovohexaborane(6). The thermal instabilities of the latter two compounds are related to previous studies. (Author)
