ω-Azolylacetophenones 1 and 2 react with dimethylformamide dimethylacetal to yield enaminones 7,8 that were converted into azolylazoles via reaction with hydrazine and with hydroxylamine. Compounds 1,2 also coupled with aromatic diazonium salts to yield arylhydrazones and reacted with nitrous acid to yield corresponding oximes.
ω-偶氮苯乙酮1和2与二甲基甲酰胺二甲基乙缩醛反应生成烯酮7,8,它们通过与肼和羟胺反应转化为偶氮唑。化合物1,2还与芳族重氮盐偶合得到芳基azo,并与亚硝酸反应得到相应的肟。
