Photoredox-Catalyzed Hydrosulfonylation of Arylallenes.
Abstract
(Het)Arylallenes undergo hydrosulfonylation under photoredox-catalyzed conditions. The reaction gives vinyl sulfones in a regio- and diasteroselective manner, employing sodium sulfinates as sulfonyl source, and Eosin Y as photocatalyst. Indol-1-yl, pyrrol-1-yl, phenyl, and naphtyl allenes might be used. Aliphatic allenes are incompatible with the reaction conditions.
