O,S-Dimethyl carbonodithioate is proposed as a suitable and safely handled reagent that can be used in the methylthiocarbonylation of primary arylamines to give S-methyl arylcarbamothioates. Optimal conditions involved a one-step procedure that was carried out at 45C in a solvent-free system, in the presence of triethyl(methyl)ammonium S-methyl carbonodithioate as a reaction promoter. The title products were obtained pure in yields that, with one exception, varied between 72 and 91% (average yield of the 12 considered examples was 83%). The by-product S,S-dimethyl carbonodithioate is also a valuable reagent. Georg Thieme Verlag Stuttgart · New York.
