Acid-catalysed reactions of the cyclohexa-2,5-dienones (3) and (14) with phenol afford diphenylethers. Quinol ethers are considered to be intermediates in these reactions, with aromatisation of the cyclohexa-2,5-dienone ring by loss of the 4-(1-alkoxy) side-chain as an aldehyde constituting the driving force.
