SCHEDULED MAINTENANCE
5-Bromoisothiazoles are attacked by nucleophiles to give 5-alkoxy- and (the hitherto unknown) 5-hydroxy-iso-thiazoles. 4-Bromo-5-hydroxy-3-methylisothiazole has been prepared by hydrolytic decomposition of the appropriate 5-diazonium fluoroborate. Preliminary studies on the tautomeric state of the hydroxyisothiazoles are reported.
