A convenient and efficient α-allylation of N-aryl tetrahydroisoquinolines has been achieved. This transformation can be realized under only visible light irradiation without the aid of transition metals or photocatalysts.

A visible light induced highly convenient and practical method for the trifluoromethyl–arylation of N-arylmethacrylamides has been developed using Umemoto*s reagent as the trifluoromethyl source.

A visible light induced decarboxylative alkylation of N-aryl tetrahydroisoquinolines has been developed using tetrachloro-N-hydroxyphthalimide esters as alkylation agents. This redox-neutral reaction can proceed without the assistance of photocatalysts, transition metals...

A highly efficient visible light-induced regioselective and stereoselective oxysulfonylation of alkynes with arylsulfonate phenol esters has been developed. This photocatalyst-and metal-free method proceeds smoothly under very mild conditions and exhibits a broad substrate scope, providing (E)-β-phenoxy vinylsulfones in moderate to excellent yields. Mechanistic studies indicated the involvement of an electron donor− acceptor complex-mediated radical process.
