(Me)(PhCC)Si(H)(Cl) (I) reacts selectively with Co2(CO)8 (II) to yield the η2-side-on coordinated compound (Me)(H)(Cl)Si2-CCPh)Co2(CO)6> (III).Treatment of III with 0.5 mol of Co2(CO)8 yields the complex (Me)(Cl)Si(ηsup

Cobalt carbonyl complexes of functional ethynylsilanes. Reactivity at the silicon atom

The reaction of various functional ethynylsilanes with dicobalt octacarbonyl was found to give the corresponding acetylene-cobalt carbonyl complexes. The reaction of Co2(CO)8 proceeded selectively at the triple bond of most ethynylhydrosilanes. Cobalt complexes of ethynylsilanes having Si-H, Si-OR, Si-Cl, and Si-Co(CO)4 bonds were obtained. The reactivity at the silicon atom in some of these complexes was studied. Reduction, alcoholysis, and aminolysis reactions were performed successfully. The reactions of strong nucleophiles such as organolithium or Grignard reagents led mainly to decomposition products. Some reactions of complexes of bis(silyl)acetylenes also were examined, and a few coordinated silacycloalkynes were isolated.
