(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.
通过含有双(triflyl)甲基作为酸性官能团的碳酸(C–H酸)催化,实现了几种内酯与酮烯丙基乙酯的 (Z)-选择性烯化;尤其是具有三个双(triflyl)甲基的三重碳酸的苯酚磷酸在催化性能上表现出色。
