SYNTHESIS AND CHARACTERIZATION OF ZEROVALENT PALLADIUM COMPLEXES

Henan Institute of Chemistry, Zhengzhou 450003

Received Date: 19 November 1990

A series of nine Pd(0)complexes(L)Pd(L')[L=bis(diphenylphosphino)methane(dppm),1,2-bis(diphenylphosphino)ethane(dppe),and 1,1'-bis(diphenylphosphino)ferrocene(dppf),respectively;L=dibenzylideneacetone(dba),2,3,5,6-tetrachloro-1.4-benzoquinone(q)and 2,3-dichloro-1,4-naphthoquinone(nq)]were synthesized and characterized by means of elemental analyses,IR,UV,¹H-NMR and ³¹P-NMR spectra.The redox wave peak potentials of the ferrocenyl group of complexes with dppf were measured by using CV method.Results showed that all the diphosphorus ligands behaved as chelating bidentate ligand and dba,q,nq were coordinated to the Pd(0)atom through their C=C moieties,not their carbonyl ones.Analytical data also showed that there were interactions between the two different ligands in each complex.
