Deuterium Exchange at Terminal Boron-Hydrogen Bonds Catalyzed by Certain Transition Metal Complexes. A Qualitative Study of Selectivity and Mechanism.

摘要

A wide variety of substrates, 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.
