以白屈氨酸为原料, 经酯化、还原、溴化、胺化等反应合成了4位带活性基团的新型含氮(NN'N)三齿配体, 配体进一步与氯化钯反应制得了Pd(II)的配合物, 并用红外、核磁、元素分析等手段进行了表征. 考察了这种钳形配合物的催化性能, 结果表明该配合物对卤代苯与乙烯基化合物的Heck芳基化反应具有较高的催化活性.

关键词: Heck芳基化反应, 三齿配体, 催化剂, 钯配合物

A new tridentate nitrogen ligand with a 4-position substituted active functional group in the pyridine ring was successfully prepared from chelidamic acid via the processes of esterification, reduction, bromization and amination, and then further reacted with palladium chloride to give the palladium(II) complex. The complex was characterized by IR, 1H, 13C NMR spectra, elementary analysis etc. The catalytic properties of the new pincer-type NN'N complex for Heck arylation of aryl halides with alkenes were investigated. The results showed that the complex had high catalytic activities.

Key words: tridentate ligand, Pd complex, catalyst, Heck arylation reaction
