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
