| Abstract
| - Reaction of the previously characterized triamidostannate complex [MeSi{SiMe2N(4-CH3C6H4)}3SnLi(OEt2)] (1) with [Cp2Zr(CH3)Cl] in toluene yieldedthe Zr−Sn complex [MeSi{SiMe2N(4-CH3C6H4)}3Sn−Zr(η5-C5H5)2(CH3)] (2) possessing a Zr−Sn bond [3.0397(2) Å]. Upon pressurizing a solution of 2 with CO (50bar) at 50 °C, it was completely converted to the acylzirconium complex [MeSi{SiMe2N(4-CH3C6H4)}3Sn−Zr(η5-C5H5)2(η2-OCCH3)] (3) by CO insertion into the Zr−CH3bond, while the Sn−Zr bond remains intact.
- Reaction of the Zr−Sn complex [MeSi{SiMe2N(4-CH3C6H4)}3Sn−Zr(η5-C5H5)2(CH3)] with CO (50 bar) at 50 °C exclusively yielded the acylzirconium complex [MeSi{SiMe2N(4-CH3C6H4)}3Sn−Zr(η5-C5H5)2(η2-OCCH3)] by CO insertion into the Zr−CH3 bond, while the Sn−Zr bond remains intact.
