We have developed a photoinduced oxidative cross-coupling of thiophenols with alcohols for O–S bond formation. The protocol uses visible light, a metal-free photocatalyst, and oxygen as the oxidant for the selective synthesis of alkyl benzenesulfonates; no ligand co-additive is necessary. Mechanistic studies suggested that the disulfide and alkyl benzenesulfinate are involved as intermediates and that the transformation proceeds by a radical pathway.

Cross-couplings between the electrophilic ketimines and isocyanates are achieved via the visible light-mediated reactivity inversion of the ketimines, affording the desired α-amino amides in high yields, with both metal and metal-free systems.
