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.
approach for the synthesis of acylsulfenic acid alkyl esters and benzoyl alkyl disulfides from thiobenzoic acids is described. This reaction uses commercially available [bis(trifluoroacetoxy)iodo]benzene (PIFA) as an oxidant under mild reaction conditions. A simple and convenient approach for the synthesis of acylsulfenic acid alkyl esters and benzoyl alkyl disulfides from thiobenzoic acids is described
