Preparation and properties of cyclodextrin–ferrocene inclusion complexes

Abstract

One-to-one inclusion complexes were obtained in crystalline state in high yield by the treatment of β-and γ-cyclodextrin (CD)with ferrocene (FcH) and its derivatives (FcR), while α-cyclodextrin formed 2:1 [CD:FcR (FcH)] complexes with ferrocene and the monosubstituted derivatives.
