## Cyclodextrin encapsulation, both in the solid state and in aqueous solution brings about a remarkable regulation of the photo-Fries rearrangement of phenyl esters and anilides. In comparison to the nonselective mixture of ortho and para-rearranged isomers along with the deacylated product obta
## Abstract The enol acetate **1b** undergoes benzoylโoxygen bond rupture upon irradiation, giving a mixture of benzophenones **4** and **5**. The primary photoโFries products **2** and **3** could not be isolated, due to a rapid intramolecular transacetylation. The acetophenone **6** rearranges to
## Abstract Enolโesters 1aโ1e undergo clean Photoโ__Fries__โrearrangements without side reactions. With anthroyl derivatives the reaction is observed only at 254 nm, not at 366 nm.
The mechanism of the photo-Pries raarrangement of aryl esters has been investigated by a number of workers.(i) In this regard, it has been reported by some workers that the rearrange-
