Direct sulfonylation of anilines mediated by visible light

C–H bond sulfonylation of anilines with the insertion of sulfur dioxide under metal-free conditions

2-Sulfonylanilines are generated in moderate to good yields through a three-component reaction of anilines, DABCO·(SO₂)₂, and aryldiazonium tetrafluoroborates under mild conditions. No metal catalysts or additives are needed for this transformation.

Merging visible-light photoredox and micellar catalysis: arylation reactions with anilines nitrosated in situ

A micellar photocatalytic system has been disclosed, which enables arylation reactions with anilines nitrosated in situ to run in water.

A visible-light photocatalytic thiolation of aryl, heteroaryl and vinyl iodides

A method for the light-driven synthesis of aryl and vinyl alkyl thioethers from a range of C(sp²)–I bonds is reported.

Catalytic, metal-free sulfonylcyanation of alkenes via visible light organophotoredox catalysis

A catalytic, redox-neutral group transfer radical addition of olefins with tosyl cyanide via visible light-induced organophotoredox catalysis has been described.
