Abstract

A convenient and efficient synthesis thiosulfonates in very good yields from thiols and sodium sulfinates involves iron(III)-catalyzed formation of sulfenyl and sulfonyl radicals in situ under aerobic conditions and their subsequent cross-coupling. The utilization of readily available, nontoxic, and inexpensive iron(III) as a catalyst and atmospheric oxygen as an oxidant makes this process green and sustainable.
