- Аннотация: Several palladium(II) complexes with 1,1'-bis(diphenylphosphino)octamethylferrocene (dppomf) and its oxidized form 1,1'-bis(diphenylphosphino)octamethylferrocenium (dppomf(+)) have been synthesized and characterized by spectroscopic and electrochemical methods. For comparative purposes, analogous Pd(II) derivatives with 1,1'-bis(diphenylphosphino)ferrocene (dppf) have been also prepared. Single-crystal X-ray analyses have been carried out for the square-planar mononuclear compounds [Pd(H2O)(2)(dppf)](OTf)(2) and [Pd(H2O)(2)(dppomf)](OTf)(2) and for the binuclear complex [Pd(mu-OPF2O)(dppomf(+))](2)(BF4)(4)(.)6CH(2)Cl(2) in which two [Pd-(dppomf(+))](3+) moieties are held together by the oxygen atoms of two bridging PO2F2- groups derived from the oxidative degradation of PF6- ions, Selected dppf and dppomf Pd(II) complexes have been employed as catalyst precursors for the metboxycarbonylation of ethene (600 psi, 1:1 CO/C2H4, 85 degreesC). It has been found that dppomf generates selective catalysts for the production of methyl propanoate, while dppf leads to a variety of low-molecular-weight oxygenates spanning from methyl propanoate to alternating oligoketones.
