Phenyl-substituted p-hydroxybenzoates

SCHEME 17.3 Photo-Fries reaction of phenyl substituted p-hydroxybenzoates. [Pg.633]

Phenyl-substituted p-hydroxybenzoates (Structure 4) have been used as light Stabilizers in polyolefins for some time. They were shown to operate through a photo-Fries rearrangement to give a more effective 2-hydroxy-benzophenone product by the following reaction sequence (Scheme 4) to give 2-hydroxybenzophenones as products [1,2]. Obviously for such a reaction to occur, the original stabilizer must absorb appreciably in... [Pg.431]
