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 2 NH⋅BH 3 (see scheme). Such Ti III –amidoborane complexes are generated in [Cp 2 Ti]‐catalyzed amine–borane dehydrocoupling reactions, for which diamagnetic M II and M IV species have been previously postulated as precatalysts and intermediates.
