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

and sulfonate esters using sodium arenesulfinates and thiophenols/phenols is disclosed. The protocol involves using inorganic and non-toxic NaI as both redox catalyst and supporting electrolyte at room temperature without oxidant and base. The reactions provide good yields of products and tolerate broad substrate scope. The mechanistic studies revealed that the reactions proceed via a radical pathway

present the first mild, one-step direct synthesis of mixed phosphorothioates through selective generation of O–P(O)–S bonds at rt under additive-free condition. Further, reactions of different model naturalproducts with 1,1-dichloro-N,N-diisopropylphosphanamine helped to present an alternative dimerization strategy. The synthetic utility of the methodology was extended for the synthesis of mixed phosphoroselenoates
absence of metal or any other additives, these transformations proceed through a spontaneous process at room temperature, which provide a convenient and compatible approach to a broad range of selenophosphates and thiophosphates.
