The acenaphthene oxidation with molecular oxygen in the presence of N‐hydroxyphthalimide (NHPI) has been investigated. It is shown that the main oxidation product is acenaphthene hydroperoxide. The phthalimide‐N‐oxyl (PINO) radical has been generated in situ from its hydroxyimide parent, NHPI, by oxidation with iodobenzenediacetate. The rate constant of H‐abstraction (kH) from acenaphthene by PINO
研究了在N-羟基邻苯二甲酰亚胺(NHPI)存在下用分子氧对的氧化作用。结果表明,主要的氧化产物是hydro啶氢过氧化物。邻苯二甲酰亚胺-N-氧基(PINO)基团是由其羟基酰亚胺母体NHPI原位生成的,它是用碘代苯二乙酸盐氧化而成的。通过PINO在乙腈中通过光谱测定从中吸取H的速率常数(k H)。还测量了动力学同位素效应和激活参数。根据我们的研究结果和现有的公开文献数据,讨论了NHPI催化di烯与双氧氧化过程的合理机理。
