We have investigated the reactions of aromatic carboxylic acids (p-XC6H4COOH, in which X = F, Cl, Br, I, NO2, CH3, H, OCH3) with methyl thiocyanate in trifluoroacetic acid.It was shown that the starting acids are converted to S-methyl benzothioates and the nitrile of the acid .In addition to starting acid, in the reaction mixtures products of the reaction of CF3COOH with methyl thiocyanate were identified. Keywords: methyl thiocyanate, trifluoroacetic acid, S-methyl benzothioates, methyl mercaptan.

S-Methyl(S-ethyl)thio(dithio)carboxinium ions were prepared by reacting methyl(ethyl) fluoride-antimony pentafluoride with carbonyl sulfide (carbon disulfide) and studied with 1H and 13C NMR spectroscopy.The ions were subsequently used in the novel carboxylation reaction of arenes to S-methyl (S-ethyl) thio(dithio)benzoates.The method was also found to be adaptable to the carboxylation of polystyrene to poly(styrenecarboxylic acid) without degradation of the polymer backbone.
