HCID 867376943-Ethoxy-2-methylisothiazolium fluorosulfonate収率 50%

実験手順

3-Ethoxyisothiazole (2.0 g, 0.015 ml) and 2 ml of methyl fluorosulfonate were heated at 50° for 1 hr. The solid was washed with ether to yield 1.9 g (50%) of 3-ethoxy-2-methylisothiazolium fluorosulfonate, mp 65°-68°. Spectral data (NMR & IR) were consistent with the assigned structure.
