A convenient synthetic method for N-acylation of sulfonamides in the presence of P₂O₅/SiO₂ is described. Carboxylic acid anhydrides and carboxylic acid chlorides were used as acylating agents and the reactions were carried out in CH₂Cl₂ or solventfree conditions. The catalyst can be recovered by simple filtration and can be used in the subsequent reactions.
