- [1,3]-Dithiolo-[4,5-d ][1,3-dithiole]-2,5-dione
-
A safe, three-step reaction sequence to [1,3]-dithiolo-[4,5- d ][1,3-dithiole]-2,5-dione starting from carbon disulfide is presented. Optimized reaction conditions, rigorous purification, and full characterization of all intermediates provide reproducibly a final product of superior quality with a melting point of 181 °C (dec.).

- ELECTROCHEMICAL REDUCTION OF CARBON DISULFIDE. SYNTHESIS OF CARBON SULFIDE HETEROCYCLES
-
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 dithiolo-1,2,3-trithiole-5-thione.
