摘　　要：以咪唑鎓盐、氯化钯和吖啶等为起始原料,经一锅法反应方便地合成了两种新颖的N-杂环卡宾-钯(Ⅱ)化合物.新化合物通过~1H NMR,^(13)C NMR和元素分析等手段进行了结构表征,结构通过X射线单晶衍射进行了确定.此外,所获得的钯(Ⅱ)化合物可以作为芳基或苄基氯化合物与芳基硼酸的Suzuki-Miyaura偶联反应高效催化剂.在优化的反应条件下,所有拓展的底物都能成功地发生反应,并得到较好的收率.Two novel N-heterocyclic carbene-palladium（Ⅱ） complexes were conveniently synthesized through one-pot reactions of imidazolium salts, palladium chloride and acridine. The new complexes have been fully characterized by 1H NMR, 13C NMR, elemental analysis, and X-ray single-crystal diffraction. Moreover, the obtained palladium（Ⅱ） complexes were the effective catalyst precursors for the Suzuki-Miyaura coupling of aryl as well as benzyl chlorides with arylboronic acids. Under the optimal conditions, all reactions proceeded successfully to give the desired products in good to almost quantitative yields.
