合成了一系列吸电子基团和供电子基团取代的N-羟基邻苯二甲酰亚胺(X-NHPI),研究了芳环上的取代基对NHPI在环己烷选择氧化反应中催化活性的影响。结果表明,吸电子基团可以增强NHPI的催化活性,吸电子能力越强,催化活性越高;供电子基团则降低了NHPI的催化活性。

A series of aryl-substituted N-hydroxyphthalimides ( X-NHPI) containing both electron-withdrawing groups and electron-donating groups have been synthesized． The effect of substitution in the aromatic ring of N-hydroxyphthalimide on catalytic activity in cyclohexane oxidation has been tested． The results showed that the electron-withdrawing groups enhance the catalytic activity of the NHPI， the electronwithdrawing ability was stronger． On the other hand， the electron-donating groups decrease the catalytic activity of the NHPI．
