including carboranes, metallocarboranes, and boron hydrides, were found to undergo catalytic isotopic exchange of terminal hydrogen with deuterium gas in the presence of various transition metal complexes. A mechanism is postulated which rationalizes the varied results and which involves oxidative addition of boron-hydrogen bonds to catalytic species.
