Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methyl fluorosulfate | HCID 9870 | — |
| Reactant | 4-Bromo-3-methoxy-1,2-thiazole | HCID 12393931 | — |
| Product | 4-Bromo-3-methoxy-2-methylisothiazolium fluorosulfonate | HCID 86737695 | 81% |
Reaction Steps
4-Bromo-3-methoxyisothiazole (8.0 g, 0.041 mol) and 10 ml of methyl fluorosulfonate were heated at 90° for 45 min. After cooling, the solid was washed with ether to yield 10.3 g (81%) of 4-bromo-3-methoxy-2-methylisothiazolium fluorosulfonate, mp 180°-182° C.
