O-Ethyl-S-cyanomethyl-dithiocarboxylate 1 reacts with carbon disulfide under phase transfer conditions to the 5-cyano-2-thioxo-1,3-dithiole-4-thiolate 2, giving with α-halocarbonyl compounds R1CH2X 6-aminothieno-1,3-dithiole-2-thiones 3. 2 can be alkylated to 4.These compounds 3 or 4 were transformed into the 1,3-dithiole-2-ones 5 or 6 respectively by heating with mercuric acetate in chloroform-acetic acid.
