In the presence of Cu2O and pyridine, arylboronicacids couple with tetraalkylthiuramdisulfides smoothly to furnish the desired phenyl dithiocarbamates in good to excellent yields. The broad substrate scope, short reaction time, commercially available cheap substrates, easy performance, and nice yields make this approach attractive.

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.

A facile synthesis of biologically important S-aryl dithiocarbamates has been demonstrated by the arynethree-componentcoupling involving CS2 and aliphatic amines. This transition-metal-free and mild reaction is scalable and operates with good functional group compatibility. Preliminary mechanistic experiments, including density functional theory studies, are also provided. Moreover, with 3-triflyloxybenzynes
