(formula presented) A new and facille approach to 4-alkylthio-1,3-dithiole-2-thione starting from easily accessible reactants was described. This approach was based on the unusual reaction of a zinc complex of 1,3-dithiole-2-thione-4,5-dithiolate with electrophilic reagents in the presence of 3-picolyl chloride hydrochloride/or 4-picolyl chloride hydrochloride/or pyridine hydrochloride.

Electrochemical reduction of 4,5-bis(alkylthio)-1,3-dithiol-2-ones (1a-d) in aprotic medium, followed by alkylation, gives tetrathioethylenes (2) in nearly quantitative yield.A similar reduction and alkylation of 1,3,4,6-tetrathiapentalene-2,5-dione (3) leads to 1 in almost quantitative yield. 4,5-Bis(alkylthio)-1,3-dithiole-2-thiones (4) gives tetrathiooethylenes under similar conditions in lower yield than 1.The mechanism of the reactions is discussed on the basis of the preparative and cyclic voltammetric results.
