The reductive coupling of alkyl or benzylic benzothiazole sulfones with arylacetylenes are performed in the presence of Hantzsch esters and K2CO3 under visible-light irradiation. The utility of this protocol is expanded to α-deuterative coupling using a deuterated Hantzsch ester, furnishing the corresponding alkenes with high deuterium incorporation.
