Abstract : The reaction of acetylene-d2 with tetraborane (10) was found to produce methyl and dimethyl derivatives of tricarbahexaborane (7) in which all deuterium present is bound to carbon, and minimal C-D cleavage occurred during carborane formation. All of the carborane products failed to undergo deuterium exchange with acetylene-d2 at 50C. The reaction of 2,4-dimethyltricarbahexaborane (7) with sodium hydride removes the bridge proton, forming 2,4-dimethyltricarbahexaborate (1-) ion. The latter species reacts with deuterium chloride to form 2,4-dimethyl-mu-deuteriortricarbahexaborane (7). (Author)
