The synthesis, characterization, and reactivity of 1,1′-bis(diphenylphosphino)osmocene (dppo) were discussed. It was found that dppo was prepared using lithiation of osmocene on n-hexane/diethyl ether, followed by reaction with chlorodiphenylphosphine. It forms a variety palladium(II) complexes showing either the κ2P,P or κ3Os,P,P bonding mode. The complex [Pd(OTs)(dppo)OTs (OTs = p-toluenesulfonate) was found to an effective precursor for the selective methoxycarbonylation of ethylene to methyl propanoate and of styrene to a mixture of methyl 3-phenylpropanoate and methyl 2-phenylpropanoate.
