摘要： 合成了双氯桥双核钯配合物[Ph2P(o-C6H4CO)PdCl]2·2CH2Cl2进行了元素分析、红外光谱表征和晶体结构测定,研究了其催化氢化性能。在30～80℃、氢分压1.0～5.0MPa的范围内。发现该配合物是催化氢化丙烯酸为丙酸的有效催化剂。晶体[Pd2Cl2(C19H14OP)2]·2CH2Cl2属P1空间群,a=0.9304(3)nm,b=1.0392(2)nm,c=1.1062(3)nm;a=102.78(2),B=97.35(3),γ=95.25(2),V=1.0264nm3,M=1032.17,Z=1,Dc=1.670g/cm3,u=13.695cm-1,F(000)=512,用1945个独立衍射精修结构,最终R=0.036.

Abstract: The interaction of Pd (CH3CN)2Cl2and 1 equivalent of o-(diphenylphosphino ) benzaldehyde in refluxing dichloromethane gives dinuclear palladium(Ⅱ) complex [Ph2P(o-C6H4CO)PdCl]2,·2CH2Cl2by the intramolecular elimination of HCl. The complex has been characterized by analytical and spectroscopic methods as well as X-ray diffraction analysis.Crystal data: [Pd2Cl2(C19H14OP)2]·2CH2Cl2,,triclinic, P1, a =0. 9304 (3) nm, b=1. 0390 (2) nm, c=1. 1062(3) nm; a=102. 78(2), B=97. 35(3), Y=95. 25(2)°, V=1. 0264 nm3,M=1032. 17, Z=1, Dc=1. 670 g/cm3, u=13. 695 cm-1. F(000) =512, final R=0. 036 for 1945 significant reflections. The complex as a catalyst for homogeneous hydrogenation of olefin has been investigated.The results indicate that the title complex is an active catalyst for hydrogenation of acrylic acid.

Key words: Dipalladium complex, o-(Diphenylphosphino) benzaldehyde. Crystal structure, Catalytic hydrogenation
