5,6-Dihydro-1,3-dithiolo[4,5-b][1,4]dithiin-2-one (3) was prepared in one step starting from thiapendione (1; [1,3]dithiolo[4,5-d][1,3]dithiole-2,5-dione) in 55% yield via 4,5-dimercapto-1,3-dithiol-2-one (2). Coupling of 3 in triethyl phosphite gave bis(
Electrochemical Synthesis of Tetrathioethylenes

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.
