A silica‐supported ionic liquid phase catalyst containing Keggin‐type anion has been prepared by covalent grafting of ferrocene‐tagged ionic liquid in a matrix of silica followed by anion metathesis reaction . This novel catalyst served as a robust heterogeneous catalyst for the synthesis of biologically active sulfonamides from 4‐toluenesulfonyl chloride and amines. Additionally, recycling experiments showed that the catalyst could be reused five times. Copyright © 2015 John Wiley & Sons, Ltd.
