repurposing n-butyl stannoic acid as a catalyst for direct amidation of carboxylicacids with amines. Notably, efficientamidation observed in comparison with all other catalytic methods reported up until now. The protocol has successfully applied to the synthesis of a variety of amides. Moderate reaction parameters, clean amidation with excellent yields of desired amides, ability to tolerate a variety
