Computational investigations suggest a metallated ketene intermedate. Ultimately, the formed enedoliate fragment can be liberated on reaction with a silane, establishing a potential pathway for s-block metal alkyl formylation catalysis.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Catalyst-free insertion of carbon monoxide into terminal Mg–C(sp3) bondsjournal articlehttps://doi.org/10.1039/D6CC00736Hhttps://pubs.rsc.org/en/content/articlelanding/2026/cc/d6cc00736hopen access547Química23 Química
