Angewandte Chemie International Edition published by Wiley-VCH GmbH.α-Silyl alkyl complexes, such as the ubiquitous MCH2SiMe3, are some of the most used organometallic building blocks and reagents. Hitherto, most reports focus on the reactive metal–carbon bond, while the carbon–silicon bond has thus far been limited to a handful of serendipitous reaction patterns. Herein, by examining a range of reactions between mononuclear Li or Na α-silyl alkyl complexes and CO, CO2, or heteroallenes (isocyanates, isothiocyanates, carbodiimides), we report tandem M─C and C─Si bond reactivity, with in-depth mechanistic understanding unveiled by computational reaction pathway studies enabled by the artificial force induced reaction (AFIR) method. By bringing the long-neglected C─Si bond reactivity to the awareness of synthetic chemists, we demonstrate that the C─Si bond should be taken into account in reaction design when using these α-silyl alkyl complexes.
