The Brønsted and Lewis acidic promoted N-acylation of sulfonamides with acetic anhydride or benzoyl chloride has been achieved using glacialacetic acid and magnetic Fe3O4@Diatomite earth. Use of acetic acid as solvent omits the need for organic bases and permits the isolation of products by filtration and precipitation. Additionally, the magnetic composite Fe3O4@Diatomite acts as a conjugate proton
使用冰醋酸和磁性Fe 3 O 4 @硅藻土可以实现磺酰胺与乙酸酐或苯甲酰氯的Brønsted和Lewis酸性促进的N-酰化反应。使用乙酸作为溶剂不需要有机碱,并允许通过过滤和沉淀分离产物。此外,磁性复合材料Fe 3 O 4硅藻土还可以作为共轭质子超强酸,实现磺酰胺化合物的酰化。
