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

Abstract: Diphenyland diethyl-silane react with an excess of octacarbonyldicobalt to give compounds of the formula R,SiCo,(CO),, ( 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 hydridotetracarbonylcobaltand heptacarbonyldicobalt-silicon compounds appear to be intermediates in the reactions.

“…With these group 14 elements, reaction of R 2 EH 2 (E = Ge or Sn) with Co 2 (CO) 8 gave dimeric cyclic complexes of type (OC) 3 Co(μ-ER 2 ) 2 Co(CO) 3 . , With E = Si, this reaction is more complex. The expected R 2 HSiCo(CO) 4 is formed, along with other polynuclear clusters, but no dimeric cyclic complex like (OC) 3 Co(μ-ER 2 ) 2 Co(CO) 3 was isolated. , …”

“…KETTLE 3 . Alle bisher unternommenen Anstrengungen zur Synthese von alkylierten ,,Silylidyn-Clustern" (CO)9Co3Si-Y (Y = Alkyl-) führten lediglich zu Methylidyn-trikobalt-Clustern des Typs (C0)9Co3C-0-SiR3, in denen das Silizium über Sauerstoff an den ^-Kohlenstoff gebunden ist [4][5][6] . Natrium-kobalttetracarbonylat wurde mit Methyl-bzw.…”
