Mercury(II) oxide oxidation of N,N-disubstituted hydroxylamines with the α and α′ carbon atoms containing one and two hydrogen atoms, respectively, gave aldonitrones in a highly regioselective manner. Removal of the α proton is involved in the rate determining step as shown by primary kinetic isotope effect.
N,N-二取代的羟胺分别被具有一个和两个氢原子的α和α'碳原子氧化的汞(II)氧化,以高度区域选择性的方式生成醛亚硝酮。如初生动力学同位素效应所示,速率确定步骤涉及α质子的去除。
