—— | chloro-5 benzisothiazol-2,1 one-3 (1H) | 55113-95-6 | C7H4ClNOS | 185.634 |
Both N-alkyl and O-alkyl derivatives of 2,1-benzisothiazolin-3-one (1) have been prepared by unambiguous syntheses. Comparison of ultraviolet spectra indicates that (1) exists in the keto form rather than as its tautomer 2,1-benzisothiazol-3-ol (2). Alkylation of the anion of (1) yields N-alkylated products.
