Abstract

The sequence of fundamental steps implicit in the conversion of a dihydroborane to a metal borylene complex have been elucidated for an [Ir(PMe3)3] system. B–H oxidative addition has been applied for the first time to an aminodihydroborane, H2BNR2, leading to the generation of a rare example of a primary boryl complex, Ln(H)M{B(H)NR2}; subsequent conversion to a borylene dihydride proceeds via a novel B-to-M α-hydride migration. The latter step is unprecedented for group 13 ligand systems, and is remarkable in offering α- substituent migration from a Lewis acidic center as a route to a two-coordinate ligand system.
