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.
5-溴异噻唑被亲核试剂攻击,生成5-烷氧基-和(迄今未知)5-羟基-异噻唑。通过适当的氟硼酸5-重氮鎓的水解分解制备了4-溴-5-羟基-3-甲基异噻唑。报道了对羟基异噻唑的互变异构状态的初步研究。
