A novel and highly efficient I2/K2CO3mediated regioselective sulfonylation of thiophenols, aryl acetylenic acid and aromatic alkynes withN-hydroxy sulfonamide has been developed.N-hydroxy sulfonamide has been used for the first time for the synthesis of these sulfones. The scope and versatility of the reaction has been demonstrated by the regio- and stereoselective synthesis of different analogs of sulfones with various structural features.

supporting information, p. 2808 - 2811 (2016/07/06)
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.
NBS-promoted sulfenylation of sulfinates with disulfides leading to unsymmetrical or symmetrical thiosulfonates

experimental part, p. 1611 - 1616 (2012/09/07)
A highly practical method to access unsymmetrical and symmetrical thiosulfonates in moderate to excellent yields has been developed through NBS-promoted sulfenylation of sulfinates with disulfides. The present process enables the use of two RS in RSSR and shows broad functional group tolerance, which represents an atom-economical and practical procedure for the synthesis of thiosulfonates. A plausible mechanism for the role of NBS as a promoter for the cleavage of disulfides generating N-(organothio)succinimide that then undergos facile sulenylation with sulfinates is proposed.
