    Photo-Fries Rearrangement of Phenyl Salicylate

    Shinzawa H,et al. Vibrational Spectroscopy, 2015, 81: 131-135.

    Phenyl salicylate is a commonly used UV filter. Changes in the spectral features were readily captured during the photo-induced chemical reaction of the phenyl salicylate by means of two-dimensional (2D) correlation spectroscopy. The photo-Fries rearrangement involves the transformation of molecules such as phenolic esters to hydroxy aryl ketones. This chemical reaction is important since the molecules generated by the rearrangement can be used as source for photoresist materials.
    Reaction Mechanism
    · When exposed to UV-irradiation, the majority of the phenyl salicylate predominantly undergoes photothermal degradation, generating oxides first.
    · Further irradiation develops 2,20 -dihydroxybenzophenone followed by the production 2,40 -dihydroxybenzo-phenome.
