Abstract
Three palladium(II) complexes Pd(L)X (X = CH3CO2, Cl, I) of the conjug ate base of 2-(diphenylphosphino)benzaldehyde benzoylhydrazone (HL) ha ve been synthesized and characterized. Pd(L)-(CH3CO2) is active in the catalytic hydrogenation of styrene, phenylacetylene and 1-octyne. Whi le styrene is hydrogenated to ethylbenzene, alkynes are mainly hydroge nated to the corresponding olefins. Stable alkynylpalladium(II) comple xes which are responsible for the loss of catalytic activity have been isolated and characterized. The X-ray structure of one of them, Pd(L) (C=C-C6H5), has been determined together with that of the Pd(L)Cl comp lex
