ORGANOCOBALT CLUSTER COMPLEXES .29. NOVEL SILICON-COMPOUNDS CONTAINING THE NONACARBONYL TRICOBALTCARBON SUBSTITUENT

The reaction of bromomethylidynetricobalt nonacarbonyl or, more effectively, of methylidynetricobalt nonacarbonyl with diverse silicon hydrides (R3SiH, Ph3SiH, Me2(EtO)SiH, RnCl3-nSiH (n = 02), etc. results in formation of silylmethylidynetricobalt nonacarbonyl complexes. Silicon-functional interconversions such as SiCl → SiOH, SiCl → SiOMe, SiOH → SiF, and SiOH → SiOSiMe3, have provided still other substituted silylmethylidynetricobalt nonacarbonyl complexes, generally in high yield. The compounds Me(HO)2SiCCO3(CO)9 and (HO)3SiCCo3(CO)9 have been incorporated into methylsilicone polymers by H2SO4-induced reactions with cyclo-(Me2SiO)3. © 1979.
