| Abstract: | Bis（ tricyclohexylphosphine ）palladium（Ⅱ） dichloride PdCl2（ PCy3 ）2 ] was prepared by reacting sodium tetrachloropalladate（Ⅱ）（ Na2 PdCl4 ）with tricyclohexylphosphine in ethanol. The syn-thesis process is simple,environment-friendly and had low requirement for the equipments. The chemical composition and structure of bis（ tricyclohexylphosphine ）palladium（Ⅱ）dichloride was determined by elemental analysis,infrared spectra and 31 P nuclear magnetic resonance. The results showed that the yield of bis（tricyclohexylphosphine）palladium（Ⅱ）dichloride reached 99. 6% under the condition of molar ratio of tricyclohexylphosphine to Na2 PdCl4 more than 2. 4 and reaction temperature 70 ℃. The product was proved to be with high purity. |
