Synthesis of Aromatic Aldehydes by CH Formylation of Aromatics with Silyl Formates Prepared from CO2 and Hydrosilanes

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
A new method has been developed for the C–H formylation of aromatic compounds using silyl formates synthesized from CO2 and hydrosilanes. This is the first report on the direct C–H formylation of aromatics with silyl formates. The formylation reactions were promoted by BBr3 or BCl3. The reaction mechanism has been clarified by DFT calculations. Despite
