Visible Light Mediated Difluoroalkylation of Alkenes Using Mercaptobenzothiazole‐Derived Sulfide Reagent

A method for the reductive difluoromethylation of alkenes with 2‐difluoromethylthio(benzothiazole) under photocatalytic conditions is described. The reaction involves the generation of the difluoromethyl radical by means of trimethyltriazinane, which serves as a precursor for the strongly reducing cyclic diaminoalkyl radical.
