Abstract

In a homogeneous solution, the photo-Fries rearrangement of 2, 5-disubstituted phenyl acetates gives ortho-hydroxyacetophenones as major photoproducts. The ortholpara ratio can be increased by using a highly viscous medium or restricted spaces such as those in zeolites. On the other hand, micellar solutions have little effect.
