  • metallosilanols;
  • oxo functionalization;
  • dicobaltoctacarbonyl


The reaction of the ferriohydridosilanes Cp(OC)2Fe-SiR2H (4a, c; R = Me, Cl) and Cp(OC)2Fe-SiMeH2 (4b) with dicobaltoctacarbonyl yields the heterobimetallic silanes Cp(OC)2Fe-SiR2-Co(CO)4 (A, R = Me; 7, R = Cl) and Cp(OC)2FeSi(Me)-Co2(CO)7 (6). Hydrolytic cleavage of the Si-Co bond in these systems forms the corresponding ferriosilanols (5a-c). In the case of the ferriosilane Cp(OC)2Fe-SiMe2H (4a) a Co2(CO)8-catalyzed conversion to the silanol Cp(OC)2Fe-SiMe2OH (5a) has been achieved.
