The cat. that got the butene : Highly active and selective diphosphite ligands are applied for rhodium‐catalyzed supported ionic liquid phase (SILP) hydroformylation and make it possible to form linear n ‐pentanal with exceptional selectivity from a mixed butene feedstock by combined isomerization and hydroformylation (see picture, vials 1–4 show typical SILP catalysts employed in this study.). The SILP catalyst is stable for more than 800 h on stream.
