Preparation, X-ray structure, copolymerization with styrene of [(μ-H)Os3(μ-OCNMe2)(CO)9{P(CH2CHdouble bond; length as m-dashCH2)Ph2}] and catalytic properties of the cluster/styrene copolymer

The complex [(μ-H)Os3(μ-OCNMe2)(CO)9{P(CH2CHdouble bond; length as m-dashCH2)Ph2}] derived from the replacement of a lightly-stabilizing NMe3 ligand in [(μ-H)Os3(μ-OCNMe2)(CO)9(NMe3)] by allyldiphenylphosphine molecule was physico-chemically and X-ray structurally characterized and served further as a metal cluster monomer to be immobilized on a polymer surface. The copolymerization of this cluster monomer with styrene was studied. It was found that the cluster molecule, when copolymerized, maintains its integrity and the overall structure. The cluster copolymers obtained have been tested as catalysts for oxidative dehydrogenation and cyclohexenol hydroxylation reactions.
