摘要

以氯亚钯酸钠为钯源与Binap反应，合成了[2,2'-双(二苯基膦)-1,1'-联萘]二氯化钯，收率达97.4%，合成原料相对廉价易得，合成过程简单、绿色环保。通过元素分析、红外光谱(IR)以及核磁共振分析(1H-NMR、31P-NMR)等手段，证实了所合成产物的组成与结构，产物具有较高纯度。%Dichloro[2,2'-bis(diphenylphosphino)-1,1'-binaphthyl]palladium(II) was prepared by reaction of 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl with Na2PdCl4. The compound could be synthesized easily under green production conditions with low cost, and reached a yield of 97.4%. The chemical structure of dichloro-[2,2'-bis(diphenylphosphino)-1,1'-binaphthyl]palladium(II) was characterized by elemental analysis, infrared spectra, 1H and 31P nuclear magnetic resonance. And the product was proved to be with high purity.
