Provided is a facile three step process for preparing 2-phenylterephthalic acid starting with p-xylene, followed by alkylation, dehydrogenation, and oxidation of the methyl groups corresponding to the origional p-xylene. The product, 2-phenylterephthalic acid, is useful as an intermediate in the synthesis of polyesters comprised of residues of 2-phenylterephthalic acid.

A mild and efficient one-pot visible light-induced method has been developed for the allylic oxidation. The oxidation of allylic systems has played a prominent role in this context as possibly the most widely applied C-H functionalization, owing to the utility of enones. The allylic C-H oxidation is relatively simple and predictable, even on a preparative scale, because active species generated at the allylic position are stabilized by the double bond.
