An enantioselective benzylic C(sp3)-H alkenylation of simple alkylarenes with vinyl bromides via photoinduced nickel catalysis was reported, which allowed the stereodivergent synthesis of both enantioenriched Z- and E-alkenes bearing aryl-substituted, allylic tertiary stereogenic centers. Interestingly, the tunable Z/E-selectivity was achieved by energy transfer catalysis via a judicious choice of the photocatalyst counteranion. This versatile strategy featured simple starting materials, mild reaction conditions, broad substrate scope, divergent Z- and E-selectivity and high enantioselectivities. Moreover, a formal asym. benzylic C(sp3)-H alkylation was also be achieved via a one-pot alkenylation/reduction sequence, providing a complementary strategy to address the notoriously challenging stereochem. control in C(sp3)-C(sp3) bond construction.
