Treatment of methyl 1,2-dimethyl- or 1-ethyl-2-methyl-cyclohexa-2,5-diene-1-carboxylate with triphenylmethyl tetrafluoroborate caused aromatisation to the methyl 2,3-dialkylbenzoates by migration of the methoxycarbonyl group. The corresponding 1-isopropyl- and 1-benzyl-cyclohexadienes gave methyl o-toluate under the same conditions.
用四氟硼酸三苯基甲基酯处理1,2-二甲基-或1-乙基-2-甲基-环己-2,5-二烯-1-羧酸甲酯,通过甲氧基羰基的迁移导致芳构化为2,3-二烷基苯甲酸甲酯。在相同条件下,相应的1-异丙基-和1-苄基-环己二烯得到邻甲苯甲酸甲酯。
