Versuchsvorschrift

Tribromoisothiazole (2.2 g, 0.007 mol) and 2.2 ml of methyl fluorosulfonate were heated at 65° for 10 min. under a nitrogen atmosphere. The resulting solid was washed with ether and benzene to yield 2.7 g (88%) of 2-methyl-3,4,5-tribromoisothiazolium fluorosulfonate, mp 121-129. Spectral data (NMR and IR) were consistent with the assigned structure.
