3,6-二(3,6-二叔丁基咔唑基)-咔唑的合成研究
Study on synthesis of 3,6-di(tert-butylcarbazolyl)carbazole
【摘要】 以咔唑为主要原料,经烃化、碘代、磺酰化、Ullmann反应和水解反应合成了3,6-二(3,6-二叔丁基咔唑基)-咔唑,五步反应总收率为50.3%,中间体及产品进行了1 HNMR检测。该合成工艺具有路线简单、操作方便、产率高等优点,适合大批量制备。
【Abstract】 3,6-Di(tert-butylcarbazolyl)carbazole was synthesized by using carbazole as the starting material via alkylation,iodination,sulfonylation,Ullmann reaction and hydrolysis reaction.The total yield of five steps was 50.3%.Structure of the product and intermediate was confirmed by 1HNMR and MS.This method has many advantages,such as easy operation and high yield,which can be feasible to large scale preparation.
