探讨了在微波作用下, 聚氯乙烯-三乙撑四胺负载钯配合物(PVC-TETA-Pd)对四苯硼钠与卤代苯的Suzuki反应的催化性能. 实验发现: 在微波功率为200 W时, 在Na2CO3, NaF, KF, NaHCO3等多种碱的存在下, 以DMF的水溶液(V∶V＝5∶3)为溶剂, 在无惰性气体保护下, PVC-TETA-Pd催化四苯硼钠与碘代苯在20 min内即可定量反应, 与常规加热方式相比, 节省了大量时间; 同时也证明了四苯硼钠的四个苯基均可参与Suzuki偶联反应; 该催化剂回收再利用3次后, 仍具有较高的催化活性.

The catalytic property of polyvinyl chloride triethylene tetraamine palladium complex (PVC-TETA-Pd) for Suzuki reaction of sodium tetraphenylborate with halogeno-benzene was examined under microwave heating. The results showed that under 200 W power, in the present of various alkalis, e.g. Na2CO3, NaF, KF, NaHCO3, and DMF-H2O (V∶V＝5∶3) used as solvent, PVC-TETA-Pd could catalyze sodium tetraphenylborate to react quantificationally with iodobenzene in 20 min without inert gas protection, and all the phenyl groups in sodium tetraphenylborate could take part in Suzuki coupling reaction. Compared with conventional heating, microwave heating could save much time. After being recycled and reused more than three times, the catalyst had still high catalytic activity.
