三芳基胺自由基正离子盐衍生物的合成

Synthesis of Triarylaminium Radical Cation Salts

三芳基胺自由基正离子六氯锑酸盐是常用的单电子氧化剂,被广泛应用于引发电子转移反应。与其他氧化剂相比具有氧化能力强、毒性小、制备简单、易于从反应体系中除去等优点。本文用4-卤代苯胺、4-碘甲苯为原料,1,10-菲啰琳为配体,氯化亚铜为催化剂,甲苯为溶剂,通过偶联反应合成了一系列三芳基胺衍生物,进而制备了几种新型自由基正离子盐。该方法具有产率高,条件温和的优点。目标化合物的结构经氢谱进行了表征。

Triarylaminium radical cation salts are widely used to initiate single electron oxidation. Compared with other oxidants,they have the advantages of strong oxidizing ability,low toxicity,facile preparation and easy removal from the reaction system. Herein,a series of new triarylaminium radical cation salts were synthesized in high yields,using anilines and iodobenzenes as the starting materials,1,10-phenanthroline as a ligand,and cuprous chloride as a catalyst in toluene. The structure of the target compounds were fully identified by ^1 H NMR.
