Acid-catalysed reactions of the cyclohexa-2,5-dienones (3) and (14) with phenol afford diphenyl ethers. 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.
环己-2,5-二烯酮(3)和(14)与苯酚的酸催化反应得到二苯醚。喹诺醚被认为是这些反应的中间体,通过失去作为驱动力的醛的4-(1-烷氧基)侧链,使环己-2,5-二烯酮环芳构化。
