state and in aqueous solution brings about a remarkable regulation of the photo-Friesrearrangement of phenyl esters and anilides. In comparison to the nonselective mixture of ortho and para-rearranged isomers along with the deacylated product obtained in organic solvents, the solid β-cyclodextrin complexes of unsubstituted esters and anilides show a remarkable ‘ortho-selectivity’. An impressive regio-selectivity’
