Fe-exchanged montmorillonite K10 - The first heterogeneous catalyst for acylation of sulfonamides with carboxylic acid anhydrides
Fe-exchanged montmorillonite K10 catalyzes a highly efficient reaction between sterically and electronically diverse sulfonamides and carboxylic acid anhydrides to furnish N-acylsulfonamides in excellent yield and high selectivity. The catalyst can also be reused several times.
