卤代有机物给环境带来了严重的污染,有机卤代物的脱卤氢化不仅可以将卤代有机物转化为其它化学品,同时也可以降低其在环境领域的污染.以Pd/C为催化剂,以三乙胺作为碱、还原剂和氢源,报道了一种钯催化邻位三唑取代卤苯脱卤氢化反应.该方法具有反应体系简单、产物收率高和催化剂可回收等特点.

The hydrodehalogenation of halogenated organic compounds which have brought serious pollution to the environment can not only transform them into other usefull chemicals, but also reduce their pollution in the field of environment. A Pd-catalyzed hydrodehalogenation of o-triazole aryl halides is introduced, taking Pd/C as catalyst and Et3N as base, reductant and hydrogen source. This strategy is highlighted by appealing features such as simple reaction condition, recyclable catalyst, and good yield etc.

Key words: aryl halides, hydrodehalogenation, Pd catalyzed, triazole, triethylamine
