The synthesis and properties of the new metal complexes 1, 6-12 with alkoxysilylmethy substituents (RO-SiR′2-CH2-MLn) is described. The complexes 14, 15 and 18 with a chloromethylsiloxy ligand were also prepared. These molecules should serve as starting compounds for the synthesis of metallasilaoxetanes. Several reactions which should lead to these new metallacycles have been performed, but it was never possible to isolate them or to proof their existence spectroscopically. However, chloride abstrac-tion from (C5H5)2Ti(Cl)CH2Si(CH 3)2OtBu (7) by silver cations led to the activation of the Si-O-R group. This indicates an interaction of the oxygen atom with the metal atom, but there was no proof for the intermediate formation of a four membered metallacycle.
