TRANSITION-METAL 1,2-DIHETEROLENES AND POLYHETEROTETRAHETERAFULVALENES: PRECURSORS OF CONDUCTING SOLIDS

Methods for synthesis and properties of oxygen-, sulfur-, selenium-, and nitrogen-containing transition-metal 1,2-diheterolenes and polyheterotetraheterafulvalenes are described.Also, the preparation and properties of some conducting salts based on these compounds are briefly discussed.

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.
