A convenient and efficient synthesis of symmetrical and asymmetric thiosulfonates from thiols and sodiumsulfinates is reported. The protocol involves iron(III)-catalyzed formation of sulfenyl and sulfonyl radicals in situ under aerobic conditions and their subsequent cross-coupling to afford thiosulfonates in 83–96% yield. The utilization of readily available, nontoxic, and inexpensive iron(III) as
