Participants

Reaction Steps

Into a solution of 1.0 g (0.0032 mole) of 2-[2-methyl-2,5-diaza-7,9-dithiabicyclo-(4.3.0)-nonane-8-yliden]-5,5-dimethyl-1,3-cyclohexanedione i 20 ml of acetone was bubbled dry hydrogen chloride with ice-cooling. After the crystalline was precipitated, to this solution was added 20 ml of ether to crystalize further the product dissolved in acetone.
