text: A photo-Fries rearrangement, i.e., homolytic cleavage of the ArO-COCH 3 bond, which releases the phenolic hydroxyl group and forms ortho and para rearrangement products, has been reported to occur upon photoyellowing of acetylated phenolic lignin model compounds (Braga and Hampp 2005) and could be one possible reason for the incomplete photostability obtained by acetylation.
