A new rhodium-catalyzed decarbonylated coupling reaction of ethyl benzo[h]quinoline-10-carboxylate and organoboron compounds that occurs through chelation-assisted sp2 C–COOEt bond activation was described. In this system CuCl played a very important role, and a five-membered rhodacycle was also involved as a key intermediate. Various functionalities were compatible in the reaction, and the desired
描述了一种新的铑催化的苯并[ h ]喹啉-10-羧酸乙酯与有机硼化合物的脱羰偶联反应,该反应通过螯合辅助的sp 2 C-COOEt键活化而发生。在该系统中,CuCl发挥了非常重要的作用,并且五元罗丹环也作为关键中间体参与其中。在反应中各种官能团是相容的,并且以良好至优异的产率获得了所需的产物。还已经使用Rh(I)模型催化剂对该反应机理进行了DFT计算。
