method for the synthesis of unsymmetrical diaryl sulfides has been developed by the C-S cross coupling of aryldithiocarbamates and aryldiazonium salts in the presence of CuI-2,2'-bipyridine and Zn. Aryldithiocarbamate compounds have been used here as thiol substitutes. The protocol shows wide substrate scope and good yields of the products.

An efficient approach for the copper-catalyzed synthesis of aryl dithiocarbamates from aryl iodides and tetraalkylthiuram disulfides in water is described. Without additional ligand and organic solvent, the coupling reaction could provide a series of S-aryl dithiocarbamates in moderate to good yields.

A highly efficient method for the synthesis of S-aryl dithiocarbamates is reported. By using tetramethylthiuram monosulfide (TMTM) and aryl boronic acids as starting materials, C(sp2)–S bond-forming reactions proceed smoothly to give the desired aryl dithiocarbamates in good to excellent yields. The methodology features a simple procedure, broad functional group tolerance and excellent yields, whilst

An efficient protocol for the copper-catalyzed preparation of aryl dithiocarbamates from aryl iodides and inexpensive, environmentally benign tetraalkylthiuram disulfides was developed. The features of mild reaction conditions, high yields, and broad substrate scope render this new approach synthetically attractive for the preparation of potentially biologically active compounds.
An efficient and convenient procedure for the S-arylation of tetraalkylthiuram disulfides by usingdiaryliodoniumsalts is explored. In the presence of CuI/KOtBu, two kinds of S-aryl dithiocarbamates are obtained in good to excellent yields at one time with no clear selectivity. This method has the advantages of efficiency, good atom economy, and broad substrate scope.
