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.
已经开发了三氟甲磺酸银(AgOTf)促进的苯的直接和温和甲酰化。利用二氯甲基甲基醚(Cl 2 CHOMe)和AgOTf的反应在低至-78°C的温度条件下将各种取代的苯甲酸酯化,而不会丢失酚羟基上的保护基。
