摘　　要：合成了一种N-杂环卡宾的钯配合物,可用于高效地催化芳基溴化物和对甲苯磺酸芳酯对芳基硼酸的Suzuki偶联反应.该反应在二氧六环溶剂中以醋酸钾为助剂、空气氛下80℃即可进行,具有收率高、催化剂容易制备等优点.A palladium N-heterocyclic（NHC） complex has been synthesized and successfully developed as an efficient catalyst for the Suzuki coupling reaction of aryl bromides and 4-toluene sulfonic acid aromatic esters with aryl boronic acids. The catalytic reaction proceeded smoothly in dioxane with potassium acetate as the additive at 80 ℃ in an air atmosphere, while the yield of the target product is excellent and the catalyst can be synthesized easily.
