Abstract

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, D_c=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
