A kinetic study of the α-cyclodextrin-mediated oxidation of methyl 4-nitrophenyl sulphide by 4-methylperbenzoic acid suggests that the stability constant for the cyclodextrin-peracid complex is two orders of magnitude greater than the value determined previously. Potentiometric studies confirmed this and showed that the 4-methylperbenzoate anion forms a complex of stability similar to that of the molecular acid. A less stable 2 : 1 cyclodextrin-4-methylperbenzoic acid complex is also observed.
