Procedure

3,4-Dichloroisothiazole (3.1 g, 0.02 mol) and 4 ml of methyl fluorosulfonate were heated at 40° for 15 min under a nitrogen atmosphere. The resulting solid was washed with ether and benzene to yield 3.4 g (63%) of 3,4-dichloro-2-methylisothiazolium fluorosulfonate, mp 159-164. Analysis calculated for C4H4Cl2FNO3S2 : C, 17.90; H, 1.49; Cl, 26.45; F, 7.90; N, 5.22. Found C, 17.74; H, 1.49; Cl, 26.49; F, 7.24; N, 5.13.
