Ultrasonic assisted rapid and eco‐friendly synthesis of an array of N ‐aryl amides is accomplished in good to better yields employing Brønsted acidic ionic liquid as promoter. The similar reaction also progressed under conventional mode of heating,but at relatively slower rate. Structurally varied 1‐aryltriazenes and aliphatic/aromatic nitriles are evaluated in this metal‐free approach and demonstrate the versatility of this protocol. A better functional group tolerance, mild reaction conditions, ultrasonic assistance, short reaction time, reuse and recycle of Brønsted acidic ionic liquid makes this method more practical and efficient to the existing methods.
