(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.
