The Et 3 N-assisted condensation of the ferriomethyl-silanol Cp(OC) 2 Fe-CH 2 -SiMe 2 OH (1) with 1 equiv of Cp 2 MCl 2 (M ) Ti (2a), Zr (2b)) leads to the formation of the iron fragment substituted heterosiloxanes Cp(OC 4) is obtained by further condensation of the M-Cl functionality of 3b with 1. The new compounds have been identified spectroscopically, and in addition, 3b and 4 have been structurally characterized by single-crystal X-ray diffraction methods.
