On heating tosylates of ethyl 2-alkyl-2-methyl-3-hydroxy-3-phenylpropanoate (R=Me, 1b; R=Et, 6) in o-dichlorobenzene at 170 °C, ethyl 1-methyl-2-phenyl- and 1,2-dimethyl-3-phenylcyclopropanecarboxylates, 3, and 8, were formed in both 5% yield, respectively, whereas the alkyl migration products, ethyl 3-alkyl-2-methyl-3-phenylpropenoates, were not produced. The mode of the reaction of the methyl group
在 170 °C 下加热 2-烷基-2-甲基-3-羟基-3-苯基丙酸乙酯(R=Me, 1b;R=Et, 6)在邻二氯苯中的甲苯磺酸盐,1-甲基-2-苯基乙酯- 和 1,2-二甲基-3-苯基环丙烷羧酸酯 3 和 8 分别以 5% 的产率形成,而没有产生烷基迁移产物,即 3-烷基-2-甲基-3-苯基丙烯酸乙酯。描述了甲基与阳离子碳的反应方式。
