Procedure

Trichloroisothiazole (10 ml) and trimethyloxonium hexachloroantimonate (7.9 g, 0.02 mol) were heated at 90° for 30 min. After cooling either (150 ml) was added and the solid collected to yield 7.8 g (73%) of product, mp >240. Spectral data (NMR & IR) were consistent with the assigned structure.
