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.

An unconventional reductive quenching cycle was developed to realize the visible-light-induced thiotrifluoromethylation of terminalalkenes. CF3SO2Na was used as an easy to handle CF3 radical source to afford the desired products in moderate to good yields. Mild reaction conditions and a broad substrate scope feature in this transformation.

New and Facile Synthesis of Thiosulfonates from Sulfinate/Disulfide/I2 System
Thiosulfonates were prepared by the iodine oxidative sulfenylation of sulfinates with various disulfides in good yields both in the presence and absence of solvent. One of the important biological applications of sulfenylation is the reaction of cyclic disulfides.

The anodic generation of symmetrical and unsymmetrical thiosulfonates is presented. The principle of the oxidation of symmetrical disulfides was expanded to the conversion of in situ generated unsymmetrical disulfides yielding the respective thiosulfonates. A strong dependency of the regioselectivity for the formation of the unsymmetrical thiosulfonates was encountered and allows their regioselective

A new method for the synthesis of secondary thiocarbamates from readily available isocyanides and thiosulfonates with broad functional group tolerance is reported. The reaction proceeds under mild reaction conditions in isopropanol and is catalyzed by inexpensive sodium iodide.
