Preparation of (nonacarbonyltricobaltmethoxy)(tetracarbonylcobalt)-silicon(IV) derivatives

Abstract

Diphenyl- and diethyl-silane react with an excess of octacarbonyldicobalt to give compounds of the formula R₂SiCo₄(CO)₁₄(R = Et, Ph). High resolution i.r. and mass spectra strongly suggest that these derivatives contain nonacarbonyltricobaltmethoxy- and tetracarbonylcobalt- groups directly bonded to silicon. The corresponding hydridotetracarbonylcobalt- and heptacarbonyldicobalt-silicon compounds appear to be intermediates in the reactions.
