Water-Soluble Triphenylphosphane-3,3',3''-tricarboxylate (m-TPPTC) Ligand and Methylated Cyclodextrins: a New Combination for Biphasic Rhodium-Catalyzed Hydroformylation of Higher Olefins
Résumé
The methylated cyclodextrins/m-TPPTC[tris(m-carboxyphenyl)phosphane trilithium salt]couples proved to be more efficient than the well-known methylated cyclodextrins/TPPTS [tris(m-sul-fonatophenyl)phosphane trisodium salt] systems interms of activities and selectivities to perform theRh-catalyzed hydroformylation of higher olefins inan aqueous-organic system. The interactions cyclo-dextrins/m-TPPTC have been fully studied byNMR spectroscopy.
