Abstract

Complexes of Group 4 metallocenes in the +3 oxidation state and amidoborane or phosphidoborane function as efficient precatalysts for the dehydrocoupling/dehydrogenation of amine-boranes, such as Me ₂NH·BH₃ (see scheme). Such Ti^III- amidoborane complexes are generated in [Cp₂Ti]-catalyzed amine-borane dehydrocoupling reactions, for which diamagnetic M^II and M ^IV species have been previously postulated as precatalysts and intermediates.
