An efficient enantioselective hydrosulfonylation of α,β-unsaturated carbonyls has been established, utilizing readily accessible sulfonyl chlorides, and facilitated by visible light irradiation in conjunction with chiral Ni-catalysis. This protocol enables the production of a diverse range of α-chiral sulfones with remarkable enantioselectivity.
