Abstract The feasibility of insertions of carbanions between two sulfur atoms has been reported when 5-(4-chlorophenyl)-4-cyano-1, 2-dithiol-3-thione (1) and tetramethylthiuram disulfide (17) were allowed to react with unsaturated 2a, b and active phosphonium salts 11a, b. The reactions afforded, mainly, 1, 3-dithiols 4a, b and 14a, b together with substituted thiophenes 10a, b and 16a, b. Reactions of 1 and 17 with α-alkylthiomethyl phosphonates ...
