Aromatic and aliphatic dithioesters, many of them new, have been easily synthesized in excellent yields by the esterinterchange reaction between carboxymethyl dithioesters and mercaptans. PMR spectra of these dithioesters and the corresponding oxygen analogues show that a strong anisotropic deshielding effect is associated with the highly polarized thiocarbonyl group.

The reaction of carboxylic acids (1) with a variety of thiols or alcohols in the presence of phosphorus pentasulfide (P(4)S(10)) as a catalyst and reagent (20-40 mol %) proceeded effectively to afford the corresponding dithiocarboxylic esters (2) in high yields.
