摘要

Aromatic and aliphatic dithioesters, many of them new, have been easily synthesized in excellent yields by the ester interchange 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.
