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-sulfonatophenyl)phosphane trisodium salt] systems in terms of activities and selectivities to perform the Rh-catalyzed hydroformylation of higher olefins in an aqueous-organic system. The interactions cyclodextrins/m-TPPTC have been fully studied by NMR spectroscopy.
