The exocyclic double bond in 4-arylidene-3-substituted-isoxazolin-5-one (I) undergoes addition reactions with Grignard reagents and with benzene in the presence of aluminium chloride. Treatment of 4-arylazo derivatives of 3-substituted-isoxazolin-5-ones (III) with Grignard reagents does not effect hetero-ring opening and only the carbonyl group of III enters into reaction, followed by elimination of
4-亚芳基-3-取代-异恶唑啉-5-酮(I)中的环外双键在氯化铝的存在下与格氏试剂和苯进行加成反应。用格氏试剂处理3-取代-异恶唑啉-5-酮(III)的4-芳基偶氮衍生物(III)不会影响杂环的打开,只有III的羰基才进入反应,然后在酸化时消除水元素,得到3-取代的-4-芳基偶氮-5-芳基异恶唑(IV)。通过有机镁化合物,镁-碘化镁混合物和/或氢化铝锂的作用,可以实现4-乙酰基-3-苯基异恶唑啉-5-酮(VI)的脱酰作用。
