2-Propen-1-yl 1,1,1-trifluoromethanesulfonate → 2-(2-Propen-1-yl)-3,4,5-trichloroisothiazolium trifluoromethane sulfonate

Participants

Reaction Steps

Trichloroisothiazole (5.7 g, 0.03 ml) and a solution of allyl trifluoromethane sulfonate (0.03 mol) in CCl4 were heated and excess CCl4 was removed by distillation until the reacting temperature reached 90° C. After heating at 90° for 30 min, the reaction was cooled and 150 ml of ether added. The solid was collected to yield 2.6 g (30%) of product, mp 103-105. Spectral data (NMR and IR) were consistent with the assigned structure.
