Asymmetric reductive (hetero)arylations of imines using aryl and heteroaryl halides have been uncovered with a chiral cobalt-bisphosphine catalyst. This approach complements the traditional strategy using preformed organometallic reagents, and it exhibits good functional group compatibility under mild conditions.
