A smooth method of synthesizing 3H, 6H-1,2-dithiolo[4,3-c]1,2-dithiole-3,6-dithione (3), and also its partial desulfuration to yield 3H, 6H-1,2-dithiolo[4,3-c]1,2-dithiole-3-one-6-thione (4) is presented. The ethylation product 5 of the monothione 4 reacts with various nucleophilic reagents to form remarkably stable adducts. The adducts of 5 with methanol, tert-butyl mercaptan, and with aniline could be isolated and characterized by their H-1-NMR spectra.
