mercaptans from alkyl and aralkyl chlorides. This consists of the condensation of sodium N,N-dimethyl-dithiocarbamate with halides followed by alkaline hydrolysis or hydrazinolysis of the resulting N,N-dimethyldithiocarbamates (IV). In the hydrazinolysis of IV, an insoluble solid by-product was formed which was identified as 3-hydrazino-4-amino-5-mercapto-4,1,2-triazole. Although this method was found to have

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.
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
