Nanosized MCM‐41‐SO3H based on ordered mesoporous silica material with a covalent sulfonic acid group was synthesized and used as acid catalyst for the new, simple, convenient and green synthesis of 2,4,5‐trisubstituted and 1,2,4,5‐tetra‐substituted imidazoles. Also some of synthesis products are new. Echo‐friendly protocol, short reaction times, easy and quick isolation of the products and excellent
合成了具有共价磺酸基的有序介孔二氧化硅材料的纳米级MCM-41-SO 3 H,并将其用作酸催化剂,用于新,简单,方便且绿色地合成2,4,5-三取代和1,2, 4,5-四取代的咪唑 还有一些合成产品是新的。此方法的主要优点是:对环境友好的方案,较短的反应时间,简便,快速的产物分离以及优异的收率。
