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.

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.
A convenient and efficient protocol for the S-arylation of sodium dialkyldithiocarbamates was developed. With the catalysis of copper(I) bromide, sodium dialkyldithiocarbamates coupled with aryl boronic acids giving the C-S coupling products smoothly in good to excellent yields. This protocol features easily available starting materials, easy performance, short reaction time, broad substrate scope
Metal-free, <i>tert</i>-butyl nitrite promoted C(sp<sup>2</sup>)–S coupling reaction: the synthesis of aryl dithiocarbamates and analysis of antimicrobial activity by ‘<i>in silico</i>’ and ‘<i>in vitro</i>’ methods for drug modification
An environmentally friendly, metal-free, and efficient C(sp2)–S couplingreaction protocol between aniline and low-cost tetraalkylthiuram disulfides was developed to synthesize aryl dithiocarbamates. The targets for developing the method included catalyst-free, base-free, mild reaction conditions, room temperature synthesis with high yields, and broad substrate scope. Apart from this, our approach
