Disposition of ferrocenes in β- or γ-cyclodextrin
Abstract
The inclusion of ferrocene in β- or γ-cyclodextrin (β-CDx or γ-CDx) has been determined to be axial or equatorial, respectively, by comparing the induced circular dichroism (i.c.d.) of 1,4,7,10,13-pentaoxa[13]ferrocenophane (1) in the presence of β-CDx with that of ferrocene in β-CDx or γ-CDx.
