The coupling of haloarenes to styrenes and 1,1-diarylethenes has been achieved with potassium tert-butoxide in the presence of N,N'-dialkyldiketopiperazines. In contrast to previously reported reactions where phenanthroline has been used to mediate the reactions, the use of diketopiperazines can lead to either 1,1,2-triarylethenes or 1,1,2-triarylethanes, depending on the conditions used.
已成功实现卤代芳烃与苯乙烯和1,1-二芳基乙烯的耦合,反应条件为存在N,N'-二烷基二酮哌嗪的氢氧化钾叔丁基。与之前使用苯并喹啉介导反应的报道不同,使用二酮哌嗪可以根据所用条件生成1,1,2-三芳基乙烯或1,1,2-三芳基乙烷。
