Water-soluble triphenylphosphane-3,3′,3-tricarboxylate (m-TPPTC) ligand and methylated cyclodextrins:: A new combination for biphasic rhodium-catalyzed hydroformylation of higher olefins

The methylated cyclodextrins/m-TPPTC [tris(m-carboxvphenyl)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.
