α‐Bromoacetophenone oxime (2) undergoes halogen substitutions with cyanide and thiocyanate ions to give 4 and 6, respectively. The oxime 2 also reacts with thiourea to give the thiadiazine 12, with malononitrile and ethyl cyanoacetate to give the pyrido[3,2‐e]oxazine 13 and the oxazine 14, respectively. With hydrazines 2 reacts to give the triazoles 15a, b.
α-溴苯乙酮肟 (2) 用氰化物和硫氰酸根离子进行卤素取代,分别得到 4 和 6。肟 2 还与硫脲反应生成噻二嗪 12,与丙二腈和氰乙酸乙酯反应生成吡啶并 [3,2-e] 恶嗪 13 和恶嗪 14。与肼2反应得到三唑15a、b。
