摘　　要：研究了四-全氟苯基卟啉过渡金属(TPFPPM,M=Co、Mn、Fe)/高价金属盐体系催化分子氧对烷基芳烃侧链氧化反应.结果表明,TPFPPCo催化乙苯及其衍生物的侧链氧化时,加入底物1/800的K2Cr2O7对反应有很好的促进作用,乙苯最高转化率达55.2%,苯乙酮收率为51.0%.该催化体系对于取代烷基苯,如正丙苯、正丁苯和对-溴乙苯也具有很好的催化效果.The side chain oxidation of alkylbenzene catalyzed by fluorinated metalloporphyrin （ TPFPPM, M = Co, Mn, Fe）/high valent metal salt with molecular oxygen has been investigated. The results showed that the addition of K2Cr2O7 [ Sub/ K2Cr2O7 = 800 （mol）] into this catalytic system could remarkably promote the catalytic performance of fluorinated metalloporphyrin for the oxidation of ethylbenzene and its derivative with molecular oxygen. The conversion of ethylbenzene reached 55.2% with 51.0% yield of acetophenone. This catalytic system also showed good catalytic performance for the oxidation of alkylbenzene, such as n-propylbenzene, n-butylbenzene and 4-ethylbromobenzene.
