EXAMPLE - Flask (125 ml) was charged with (1,3-diethyl-imidazolidine-2-thione) (1 g) and water (30 ml). Bromine (Br2) (0.2 ml) was added dropwise. The solution was stirred for 1 hour at room temperature. In a separate flask (50 ml) filled with water (20 ml), lithium bis(trifiuoromethanesulfonyl)imide (LiTFSI) (1.81 g) were dissolved. The mixture was then added to the previous solution to give a yellowish oil of 1,3-diethyl-imidazolidine-2-thione disulfide compound. The compound was extracted with ethylene oxide (Et2O) (50 ml). The organic layer was separated and dried with anhydrous magnesium sulfate. The organic layer was concentrated using rotative evaporator. A yellowish oil 1,3-diethyl-imidazolidine-2-thione disulfide was obtained.
