Octyl triflate → 2-Octyl-3,4,5-trichloroisothiazolium trifluoromethane sulfonate

Participants

Reaction Steps

Trichloroisothiazole (6.6 g, 0.035 mol) and n-octyl trifluoromethane sulfonate (7.5 g, 0.0286 ml) were heated at 110° for 2 hrs. After cooling, 150 ml of ether was added and solution cooled in a dry ice/acetone bath. The ether was decanted and the brown oil dried to yield 4.0 g (31%) of product. Spectral data (NMR and IR) were consistent with the assigned structure.
