摘要：

The stability constants of the complexes of alpha-cyclodextrin and 4-methyl-, 4-nitro-, 4-sulfonato- and 3-chloro-substituted perbenzoic acids, perbenzoates and benzoates, but not benzoic acids, show linear free energy relationships. In contrast to alpha-cyclodextrin, the stability constants of the beta-cyclodextrin complexes of perbenzoic acid and benzoic acids do show the same trend. The stability constants are discussed in terms of the orientation of the guest species in the cyclodextrin cavity.
