Under solvent-free conditions, various unsymmetrical benzoyldisulfides and symmetrical novel biscarbonyldisulfides were easily prepared in good yields at room temperature by the mixing of thiosulfonates with thiocarboxylic S-acids in the absence or presence of an amine.

NBS‐Promoted Sulfenylation of Sulfinates with Disulfides Leading to Unsymmetrical or Symmetrical Thiosulfonates
practical method to access unsymmetrical and symmetricalthiosulfonates in moderate to excellent yields has been developed through NBS‐promotedsulfenylation 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
Phenylboronic acid-catalyzed tandem construction of S–S and C–S bonds: a new method for the synthesis of benzyl disulfanylsulfone derivatives from <i>S</i>-benzyl thiosulfonates
A unique phenylboronic acid-catalyzed dimerization-sulfonylation of S-benzyl thiosulfonates has been disclosed. A metal-free tandem construction of S-S and C-S bonds is an operationally simple method to access a wide range of benzyl disulfanylsulfone derivatives in high to excellent yields. Moreover, the robustness of this tandem transformation has been demonstrated by gram-scale reactions, and a plausible
