Resumo

The reaction of (RCp)2Zr(OCH3)Cl with two molar equivalents of ClMgCH2OCH3 yields (RCp)2Zr(CH2OCH3)2 (6). Thermolysis of 6 at 70° gives ethylene and (RCp)2Zr(OCH3)2. The low temperature dynamic NMR spectra of 6 indicate the presence of a η2-CH2OCH3 ligand. It is suggested that the thermally-induced insertion of the meatallaoxirane methylene unit into the remaining ZrCH2OCH3 σ-bond initiates the reaction sequence leading to CH2CH2 and dimethoxyzirconocene.
