A chiral imidazole iminopyridine as a ligand enables a highly enantioselective cobalt-catalyzed hydroboration of diaryl ketones with pinacolborane to provide chiral benzhydrols in very good yields and ee. This protocol could be carried out in a gram scale under mild reaction conditions with good functional group tolerance.
