A highly efficient sulfonylation of thiols has been achieved through the metal-free NaI/TBHP-mediated cross-coupling of sulfonyl hydrazides and thiols at roomtemperature. This method provides a convenient and practical route to thiosulfonates in 84–99% yields (39 examples) with wide functional group compatibility.

sulfonylation of thiols was performed by using sodium sulfinates under an oxygen atmosphere. The procedure afforded thiosulfonates in good yields by using a CuI–Phen·H2O (Phen = 1,10-phenanthroline) catalyst and tolerated numerous combinations of arene- and alkanethiols with sodium sulfinates. Furthermore, it was found that the coupling of diaryl disulfides with sodium arylsulfinates proceeded in air and both

A visible-light-triggered radical cascade sulfonylation/aryl migration/desulfonylation and C–S/Se bond formation reaction of butenyl benzothiazole sulfone with thiosulfonates or selenosulfonates is developed. This study affords the 1,2,4-trifunctionalization of butenyl benzothiazole sulfone derivatives under mild conditions.
