Highly Selective Catalyst Systems for the Hydroformylation of Internal Olefins to Linear Aldehydes

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‐F3C6H2 (inste...

Zusammenfassung:	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‐F3C6H2 (instead of Ph), 1 a) show a remarkable high activity and n:i selectivity in the rhodium‐catalyzed hydroformylation of internal olefins (see scheme).
