Visible-light-induced iron-catalyzed S–N cross-coupling of thiols with dioxazolones

Abstract

An efficient visible-light induced iron-catalyzed S–N coupling of thiols with dioxazolones under mild conditions has been developed. The reaction proceeds under ligand- and photosensitizer-free conditions, and has features of satisfactory yields, broad functional group tolerance, and an easy operation procedure. Preliminary mechanistic investigations showed that these reactions were conducted via a radical pathway.
