Copper-catalyzed N-arylation of imidazoles can be accomplished using (CuOTf)2·benzene as a copper source and Cs2CO3 as a base in xylenes at 110–125 °C. Addition of 1,10-phenanthroline (phen) and trans,trans-dibenzylideneacetone (dba) was crucial to the success of the process. The products, N-arylimidazoles, were isolated in high yields.
铜催化的咪唑的N-芳基化反应可以使用(CuOTf)2 ·苯作为铜源,而Cs 2 CO 3作为二甲苯中的碱在110–125°C下完成。添加1,10-菲咯啉(phen)和反式,反式-二苄基丙酮(dba)对于该方法的成功至关重要。以高收率分离出产物N-芳基咪唑。
