摘　　要：将Pd(OAc)_(2)与2-二苯膦基苯甲醛络合,再与甲醛、尿素缩合反应制备脲醛树脂,得到固载钯催化剂。用固载钯催化剂进行一系列芳基硼酸与芳基卤代物的Suzuki耦联反应。研究结果表明,固载钯催化剂在温和的反应条件下催化合成联苯类化合物,收率>86%,合成的固载钯催化剂具有良好的重复利用性。Pd(OAc)_(2) was complexed with 2-(diphenylphosphino)benzaldehyde, and then condensed with formaldehyde and urea to prepare urea formaldehyde resin for the supported catalyst of palladium. A series of Suzuki coupling reactions between aryl boric acid and aryl halide were performed using the obtained supported catalyst. The results showed that the immobilized catalyst could afford bi-aryl compounds efficiently under mild reaction conditions and with yields over 86%. This resin supported palladium catalyst has also showed good reusability.
