Article abstract of DOI:10.1021/jo00317a025

Detailed procedures for the electrochemical reduction of carbon disulfide in N,N-dimethylformamide and acetonitrile are given.The synthetic utility of the method is demonstrated by the preparation of several thio-substituted derivatives of tetrathiafulvalene.Cyclic voltammograms of the tetrapotassium salt of the tetrathio anion of tetrathiofulvalene indicate four successive electron-transfer steps and in situ formation of a C6S8 species.Oxidation of the CS2 electrolysis solutions produces a compound which is tentatively identified as <1,3>dithiolo<4,5-d>-1,2,3-trithiole-5-thione.
