Nucleophilic addition of sulfonamides and carboxamides to simple alkenes proceeded smoothly using a proton-exchanged montmorillonite catalyst. The spent catalyst was recovered easily from the reaction mixture and was reusable at least five times without any loss of activity. The unique acidity of the proton-exchanged montmorillonite (H-mont) catalyst was found to be applicable to additional reactions: substitution of hydroxyl groups of alcohols with amides and anilines.
使用质子交换蒙脱石催化剂，磺酰胺和羧酰胺与简单烯烃的亲核加成反应顺利进行。废催化剂很容易从反应混合物中回收，并且至少可以重复使用五次而活性没有任何损失。发现质子交换蒙脱石（H-蒙脱石）催化剂独特的酸性适用于其他反应：醇的羟基被酰胺和苯胺取代。
