Molecular Recognition between Chemically Modified β‐Cyclodextrin and Dec‐1‐ene: New Prospects for Biphasic Hydroformylation of Water‐Insoluble Olefins

Abstract

A conversion of up to 100% and a selectivity for aldehyde formation of up to 95% is achieved in the Rh-catalyzed hydroformylation of dec-1-ene in the two-phase system water/alkene in the presence of partially methylated β-cyclodextrins [Eq. (a); R = Me; acac = acetylacetonate]. These remarkable results are attributed to the formation of an alkene/cyclodextrin inclusion complex as well as to the solubility of the chemically modified cyclodextrins in both phases.
