Photo-Claisen Reactions of Alkyl Aryl Ethers

3 PHOTO-REACTIONS OF ARYL ESTERS IN POLYMER MATRICES. KINETIC INFORMATION FROM CONSTANT INTENSITY IRRADIATIONS 

Control over the course of the rearrangements of aryl esters can be achieved when the host matrix can interact with the ester and its intermediates through electrostatic or H-bonding interactions. Zeolites and Nafion membranes are two polymeric matrices in which such studies have been conducted. As mentioned above, the positions of the radical centers of the acyl radicals are known to be very near the oxygen atoms of their aryloxy partners at the moment of birth of the radical pairs from the excited singlet state of an aryl ester in all media all subsequent diffusion
