摘    要:本综述以催化活性中心的原子种类为分类标准,着重于催化活性物种和催化反应机理的研究,系统地总结了自90年代以来苯及其芳烃化合物羟化合成在均相催化体系的研究进展.从研究趋势分析,人们从简单的无机盐均相催化体系过渡到合成仿生含氮配体的络合物作为催化剂的液-液两相催化体系,目前以铁、钒、铜和钯为催化活性中心的配合物液相催化体系的研究比较集中.从研究机理上来看,研究者运用多种研究手段和方法,提出了在各自研究体系中的*OH、高价金属氧配合物、金属氧或过氧或氢过氧化合物(或自由基)的羟化活性物种的自由基机理和配合物机理等.

关 键 词:芳烃化合物  均相/液相  催化羟化反应  催化活性物种  催化反应机理

Abstract:One-step hydroxylation of aromatics is an intriguing topic in catalysis f o r its useful materials in industry and organic synthesis for more than a century . This review systematically outlines the progress of catalytic hydroxylation of aromatics in liquid/homogeneous phase systems with the emphasis on the acti ve species and reaction mechanisms based on the different active center of atoms such as i ron, vanadium, copper and palladium since 1990's. Developing a two-phase mimicb i ological catalytic system seems to be primary trend by synthesis a kind of compl ex containing N, O ligands for liquid aromatic hydroxylation to overcom e the drawbacks of traditional catalytic systems. Several active species of hydr oxo radical, high value metal oxo and peroxo and hydroxo as well as mechanism of radicals and complexes were suggested via using advanced analytic technologies . Though some of these mechanisms are still disputable, this review could of fer a more thorough consideration of mechanisms of hydroxylation for unde rstanding some reactions more profoundly.
Keywords:aromatics  homogeneous/liquid system  catalytic hydroxylation  active species  mechanism
