Transamidation Catalyzed by a Recoverable and Reusable PolyDMAP‐Based Hafnium Chloride and Montmorillonite KSF

Abstract In this article, we described the use of an easily available polymer‐based hafnium chloride and montmorillonite KSF catalyst (HfCl4/KSF‐polyDMAP) in transamidation under relatively mild conditions. This metal catalyst can be easily recovered and reused in this reaction to give the corresponding amides in good yields.
