The tail-to-tail oligomerization of N,N-dimethylacrylamide catalyzed by N-heterocyclic carbenes (NHCs) was investigated, giving the dimerization and trimerization products in a moderate combined yield. Reaction intermediates involved in the new oligomerization have been observed by NMR and ESI-MS. We showed the first NHC-catalyzed cross coupling of methyl methacrylate and N,N-dimethylacrylamide, and the reaction of benzaldehyde/benzoin with N,N-dimethylacrylamide.

N-杂环卡宾催化N，N-二甲基丙烯酰胺（DMAA）的尾到尾低聚反应以及DMAA与苯甲醛的Stetter反应的研究

研究了N-杂环卡宾（NHCs）催化的N，N-二甲基丙烯酰胺的尾到尾低聚，以适中的合并收率得到了二聚和三聚产物。通过NMR和ESI-MS已经观察到涉及新的低聚的反应中间体。我们展示了甲基丙烯酸甲酯和N，N-二甲基丙烯酰胺的第一个NHC催化交叉偶联，以及苯甲醛/安息香与N，N-二甲基丙烯酰胺的反应。
