Abstract

The reactions of [Os-3(mu-CO)(CO)(9){mu(3)-eta(2)-Me3SiCCC CSiMe3}] with phosphorus donor ligands (PPh3, PEt3, P(OEt)(3), PHPh2 and a diphosphine; Ph2PCH2PPh2 (dppm)) afford carbonyl mono-substitution products [Os-3(mu-CO)(CO)(8){mu(3)-eta(2)-Me3SiC2C2SiMe3}] even in the case of the bidentate phosphine dppm. All the complexes have been characterized by IR and multinuclear NMR spectroscopy and for 2 (L = PPh3), 3 (L = PEt3), 4 (L = P(OEt)(3)) and 5 (L = eta(1)-dppm) the structures have been confirmed by single- crystal X- ray analysis. The structural analyses show that in all four clusters the substitution has occurred at one of osmium equatorial sites that is sigma- bonded to the mu(3)-eta(2)-alkyne.
