First evidence of molecular recognition between cyclodextrins and a water-soluble ligand used in aqueous phase organometallic catalysis

Abstract

The formation of inclusion complexes between the water-soluble phosphane P(m-C₆H₄SO₃Na)₃ and β- and γ-cyclodextrins was proved by UV-vis, circular dichroism and ¹H and ³¹P NMR spectroscopy. Premier exemple de complexes d'inclusion entre des cyclodextrines et un ligand hydrosoluble utilise′ en catalyse biphasique. Re′sume′: La formation de complexes d'inclusion entre la triphe′nylphosphine trisulfone′e et les β- et γ-cyclodextrines a e′te′ observe′e par spectroscopie RMN et UV-vis.
