The lead tetraacetate oxidation of aldoximes at low temperature has benn studied. Oxidation of aliphatic and aromatic syn-aldoximes affords nitrile oxides. Aliphatic anti-aldoximes lead to dimeric 1-acetoxy-1-nitroso-alkanes and secondary products. Aromatic anti-aldoximes afford arylaldazine-bis-N-oxides which decompose on heating to nitrile oxides and aldoximes. Mechanisms are proposed which require
已经研究了在低温下醛肟的四乙酸铅氧化。脂族和芳族合成醛肟的氧化提供了腈氧化物。脂肪族抗醛肟导致二聚的1-乙酰氧基-1-亚硝基-烷烃和副产物。芳族抗醛肟类化合物提供芳基aldazine - bis -N-氧化物,该化合物在加热时分解为腈氧化物和醛肟类。被提出的机制需要亚氨氧基自由基如在氧化的中间体反-aldoximes,而氧化顺-aldoximes出现协调一致地进行。
