Stable free radicals obtained by the action of lead tetra-acetate on the oximes of cyclopentanone, cyclohexanone, 4-butylcyclohexanone, acetone, heptan-2-one, and heptan-4-one are tentatively assigned structures corresponding to the addition of two acetoxy groups to the CN bond of the oximes, and are characterised by their electron paramagnetic resonance (e.p.r.) spectra. The corresponding acetoxy-nitroso
通过四乙酸铅作用于环戊酮,环己酮,4-丁基环己酮,丙酮,庚烷-2-酮和庚烷-4-酮的肟的作用而获得的稳定的自由基是与两个乙酰氧基的加成相对应的暂定结构。在肟的C N键上存在,并以其电子顺磁共振(epr)光谱为特征。分别生成了相应的乙酰氧基-亚硝基自由基阴离子,并通过epr进行了表征。衍生自1-乙酰氧基-1-亚硝基-4-叔丁基环己烷的自由基阴离子对氮的超精细偶联具有构型效应。提供证据表明四乙酸铅和肟之间同时存在两个反应。
