To 0.255 g (0.001 mole) of 1,3-dimethyl-2-[(3-chloro-2-oxopropyl)thio]-1H-imidazolium chloride was added a solution of 0.156 g (0.001 mol) of 1,3,4,5-tetramethylimidazoline-2-thione in 5 mL of ethanol and the reaction mixture was stirred for 3 hours at ambient temperature. At the end of this period, the solvent was evaporated and the residue was crystallized from isopropyl alcohol-acetonehexane to obtain the desired 2-{(3-[(1,3-dimethyl-1H-imidazolium-2-yl)thio]-2-oxopropyl)thio}- 1,3,4,5-tetramethyl-1H-imidazolium dichloride compound as a hygroscopic solid.
