The reactions of Z isomers of alkylaromatic 1,2-hydroxylamino oximes containing the hydroxylamino group at the primary or secondary carbon atom with diacetyl afford 6-acetyl-5,6-dihydro-4H-1,2,5-oxadiazines. The reactions of these compounds with alkylaromatic 1,2-diketones produce N-substituted α-aroylnitrones or 6-aroyl-5,6-dihydro-4H-1,2,5-oxadiazines or, alternatively, their tautomeric mixtures
在伯或仲碳原子上含有羟基氨基的烷基芳族 1,2-羟基氨基肟的 Z 异构体与双乙酰反应得到 6-乙酰-5,6-二氢-4H-1,2,5-恶二嗪。这些化合物与烷基芳族 1,2-二酮的反应产生 N-取代的 α-芳酰基硝酮或 6-芳酰基-5,6-二氢-4H-1,2,5-恶二嗪或它们的互变异构混合物。
