実験手順

To a solution of 3.4 g (0.02 mole) of anhydrous zinc chloride in 130 ml absolute ethanol was added a solution of 2-methyl-3-isothiazolone in 20 ml of absolute ethanol. The clear solution was stirred at room temperature for 30 minutes. Concentration yielded a tan solid. The solid was triturated with ether, filtered, and dried to yield 8.4 g (92%) of bis-(2-methyl-3-isothiazolone) zinc(II)chloride, m.p. 148°-151° C.
