Molecular Encapsulation of Half-Sandwich Complexes of Iron with Cyclodextrins: New Laminar Materials

摘要: The treatment of β- and γ-cyclodextrins with the half-sandwich complexes iron afford inclusion compounds CpFe(L2)X⋅CD (β γ) (X = Cl, I; L CO; L2 dppe, dppe (Ph)2P(CH2)2P(Ph)2), [CpFe(L2)L-]PF6⋅CD L- neutral donor ligands and[(Cp(dppe)Fe)2-µ-CN]PF6⋅2CD γ). [Cp(dppe)Fe-NCCH3]PF6⋅γ-CD [Cp(dppe)Fe-(η1-dppm)]PF6⋅γ-CD have a laminar structure. γ-cyclodextrin encapsulation effect on electro-oxidation binuclear complex was studied using cyclic voltammetry.The electron-transfer reactions associated oxidation two different N-bonded C-bonded organometallic fragments are substantially affected by β γ encapsulation.
