反応手順
2-Methyl-3,4,5-trichloroisothiazolium fluorosulfonate (16.9 g, 0.058 mol) was added in portions to 150 ml of a saturated sodium acetate solution. After stirring for 30 min. the solid was collected, washed with water, and recrystallized from ethanol to yield 7.5 g (70%) of 4,5-dichloro-2-methyl-4-isothiazolin-3-one, mp 119°-120°.
