ω-Chloroisonitrosoacetophenone was treated with ethylenic and acetylenic dipolarophiles to afford 3-benzoylisoxazolinines and -isoxazoles, respectively. With m-nitrobenzaldoxime or m-nitrobenzonitrile, it yielded 3-benzoyl-5-(m-nitrophenyl)-1,2,4-oxadiazole. The phenylhydrazones of the 3-benzoylisoxazole and -oxodiazole thus produced were converted to the corresponding 1,2,3-triazoles thermally or
ω-氯异亚硝基苯乙酮用烯属和炔属偶极体处理,分别得到 3-苯甲酰基异恶唑啉和 -异恶唑。用间硝基苯甲醛肟或间硝基苯甲腈生成 3-苯甲酰基-5-(间硝基苯基)-1,2,4-恶二唑。由此产生的3-苯甲酰基异恶唑和-恶二唑的苯腙通过加热或用碱处理转化为相应的1,2,3-三唑。3-苯甲酰基-5-苯基异恶唑的光诱导重排得到2-苯甲酰基-5-苯基恶唑。用氮丙啶处理ω-氯异亚硝基苯乙酮得到一种新型的氮丙啶肟,它被转化为2-苯甲酰恶唑啉。
