3-Hydroxyisothiazole exists as the lactim in nonpolar solvents, the lactam form predominating in aqueoussolution. Acylation, although extremely rapid in nonpolar solvents, depends on the relative rates of reaction of the two tautomers rather than on their relative proportions. The size of the acyl group, and the steric requirements of the catalyst, are shown to be the critical factors in determining

This disclosure relates to a novel class of 3-alkoxy-2-alkylisothiazolium salts. These salts have been found to be useful in controlling the growth of bacteria and fungi. They have also been found to be useful intermediates in the preparation of known antibacterial and antifungal compounds.
