An unprecedented role of an imidazolium Brønsted acidic ionic liquid is found in the formation of 2,2-disubstituted quinazolin-4(1H)-one derivatives. Both the C2-H of the imidazolium moiety and an acidic proton are necessary and simultaneously take part in catalysis.

布朗斯台德酸离子液体在2-氨基苯甲酰胺与酮环化中的显着协同作用

在形成2,2-二取代的喹唑啉-4(1 H)-一衍生物中发现了咪唑类布朗斯台德酸性离子液体的空前作用。咪唑部分的C2-H和酸性质子都是必需的,并且同时参与催化。
