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.
