A silver trifluoromethanesulfonate (AgOTf)-promoted direct and mild formylation of benzenes has been developed. The reaction utilizing dichloromethyl methyl ether (Cl2CHOMe) and AgOTf powerfully formylated various substituted benzenes under temperature conditions as low as -78 °C without losing the protecting groups on the phenolic hydroxyl group.
一种三氟甲磺酸银(AgOTf)促进的苯的直接温和甲酰化方法已被开发出来。该反应利用二氯甲基甲醚(Cl2CHOMe)和 AgOTf,在低至-78°C 的温度条件下,强力地将各种取代的苯甲酰化,而不会使酚羟基上的保护基团失去。
