Abstract

The reactivity of sulfur towards thiocarboxylate ions RC (O) Sa (R= Ph 1, Me 2, But 3) has been studied by spectroelectrochemistry in N, N-dimethylacetamide. For 2a–3a, two parallel and partial reactions, for which equilibrium constants have been determined, led to:(i)[RC (O)] 2S2-b species and S3·-/S82-polysulfide ions and (ii) RC (O) S2 ions c; only traces of 1c were detected by voltammetry. As previously observed with thiolate ions, our results are ...
