Treatment of bis(dimethylsilyl)acetylene 1 with more than two molar amount of octacarbonyldicobalt in cyclohexane gave the complex [(CO)4CoSiMe2C≡C–SiMe2Co(CO)4]Co2(CO)6, while treatment of 1 with one or 1.5 molar amount of octacarbonyldicobalt produced the complexes [HSiMe2C≡CSiMe2H]Co2(CO)6 and [HSiMe2C≡CSiMe2Co(CO)4]Co2(CO)6, respectively. The reactions of dimethyl(phenylethynyl)silane and its homologs with Co2(CO)8 were also investigated.
