European Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.
