The ratio of ortho to para isomers in chlorination of acetanilide and benzanilide is changed in favour of the para isomer when the reactants are entrapped in cyclodextrins or amylose. The dissociation constant and the time-averaged position of acetanilide in the α-cyclodextrin cavity have been determined by proton and carbon-13 nuclear magnetic resonance spectroscopy.
