Biphasic Hydroformylation Using Ionic Liquids

摘要

Two different approaches for the biphasic hydroformylation of l-octene using ionic liquids are presented in detail. a) the Pt-catalyzed hydroformylation in chlorostannate ionic liquids; b) the Rh-catalyzed hydroformylation in hexafluorophosphate systems. For the latter case, the use of special ionic ligands is required to achieve full catalyst immobilization in the ionic liquid. The synthesis and application of successful cationic ligands systems is described.
