摘要 通过含酯基或酰基吸电子基团的溴苯或碘苯和苯衍生物(苯、甲苯、二甲苯,二苯基甲醚)的光催化偶联反应合成了一系列联苯衍生物,研究了光催化脱卤化氢偶联反应的最佳反应条件,并讨论了取代基对产率的影响. A series of biphenyl derivatives were synthesized by photocatalytic reactions of benzene derivatives（ benzene, toluene,1,4-dimethylbenzene,oxydibenzene） with halobenzene which contains an electron withdrawing group（Ester group,Acyl group）. The optimal conditions for this dehydrohalogenative coupling reaction were determined and the influence of substituents on the yields were also discussed.
