An efficient pincer-ligand-based cobalt-complex-catalyzed allene hydroboration affording Z-allylic boronates is described. The reaction demonstrates an excellent regio- as well as Z-stereoselectivity and a wide substrate scope that tolerates many functional groups. Based on solvent-assisted electrospray ionization mass spectrometry (SAESI-MS) studies, a rationale for the cobalt-catalyzed hydroboration involving the highly selective insertion of an allene into the Co?H bond to form Z-allylic cobalt intermediates is proposed.

Hydrozirconation of olefins followed by exposure of the resulting alkylzirconium species to catalytic CuCN in the presence of activated halides or phosphonates gives rise to products of aklkylation in good yields under mild conditions.
