Redox-triggered hydroarylation of o-（hydroxyalkyl）arylalkynes with arylsulfonyl chlorides using visible light catalysis

A new radical-mediated method for the synthesis of 1-（2-（1,2-diarylvinyl）phenyl）ethan-1-ones by the redox hydroarylation of o-（hydroxyalkyl）arylalkynes with arylsulfonyl chlorides is described. This visible light catalysis method proceeds via a sequence of the radical addition of aryl group across t...

Summary:A new radical-mediated method for the synthesis of 1-（2-（1,2-diarylvinyl）phenyl）ethan-1-ones by the redox hydroarylation of o-（hydroxyalkyl）arylalkynes with arylsulfonyl chlorides is described. This visible light catalysis method proceeds via a sequence of the radical addition of aryl group across the C？C triple bond, protonation and redox reaction, and represents a new redox transformation reaction directed by a neighboring hydroxyl group.
