摘要/Abstract
在前期工作的基础上，设计合成了一系列吡啶乙醇类双[N，O]环钯配合物，以该类环钯配合物为催化剂，通过Fujiwara-Moritani反应，在相对温和的反应条件下（2 mol%催化剂，30℃，空气环境中）即可高效实现噻吩、呋喃类芳杂环与各类烯烃的偶联，并以中等到高等的分离产率得到相应的目标化合物.进一步通过动力学实验和ESI（+）-MS同步检测，推测该反应是通过协同的金属化/去质子化（CMD）机理进行.

A series of bis(alkoxo)palladium complexes (2 mol%) based on pyridine-containing alcohol ligand were tested for Fujiwara-Moritani reaction of thiophenes/furans with various olefins. The desired products were isolated in moderate to excellent yields under mild conditions. A possible concerted metalation-deprotonation (CMD) pathway for this transformation was proved by control experiments and ESI(+)-MS analysis.
Key words: bis(alkoxo)palladium complex, Fujiwara-Moritani reaction, CMD pathway, pyridine-containing alcohol ligand
