摘　　要：芳基氟化物和氯化物结构稳定、种类繁多、价格相对溴化物和碘化物更为廉价,应用较为广泛.目前该类化合物的应用已经造成了严重的环境问题.研究发现将碳卤键转化为碳氢键能够增强该类物质的可降解性.所以氟代、氯代芳香化合物氢化脱卤反应对环境保护具有重要的意义.本文主要讲述了芳基氟化物和氯化物的氢化还原反应,简述了氟代、氯代芳香化合物氢化脱卤反应研究的现状,强调了不同形式的金属和非金属催化剂对氟代和氯代芳香化合物的脱卤素作用.同时也描述了一些新的脱卤素方法,如:电催化脱卤素和光催化脱卤素方法.Aryl fluorides and chlorides are widely used because of its unique advantages, such as stable structure, various species, cheaper prices than bromides and iodides. The compouonds and their derivatives have caused serious environmental problems. It was found that the transformation of this material s carbon-halogen bond to a carbon-hydrogen bond can increase its degradability. Therefore, the hydrodehalogenation reaction of fluoro and chloroaromatic compounds is of great significance for environmental protection. The article describes the hyorogenated reduction of aryl fluorides and chlorides and their current status of studies. The dehalogenation of fluorinated and chlorinated aromatic compounds by different metal and nonmetal catalysts was emphasized. New dehalogenation methods such as electrocatalytic dehalogenation and photocatalytic dehalogenation were also described.
