Readily accessible and highly efficient : Substituted 2,2′‐bis(diphenylphosphanylmethyl)‐1,1′‐binaphthyl (NAPHOS) ligands 1 can be readily prepared from 2,2′‐bis(dichlorophosphanylmethyl)‐1,1′‐binaphthyl. Especially ligands with electron‐withdrawing aryl substituents (for example, 3,4,5‐F 3 C 6 H 2 (instead of Ph), 1 a ) show a remarkable high activity and n : i selectivity in the rhodium‐catalyzed hydroformylation of internal olefins (see scheme).
