(Z)-Selective olefination of several lactones with ketene silyl acetals was achieved by the catalysis of carbon acids (C-H acids) having a bis(triflyl)methyl group as an acidic functionality; in particular, the triple carbon acid having three bis(triflyl)methyl groups in phloroglucinol shows an excellent catalytic performance.
通过具有双（三氟甲基）甲基作为酸性官能团的碳酸（C-H 酸）的催化，实现了几种内酯与烯酮硅基缩醛的（Z）选择性烯丙基化反应；特别是在均苯三酚中具有三个双（三氟甲基）甲基的三碳酸表现出优异的催化性能。
