An ultrasound‐accelerated route for an expeditious N ‐arylation of NH ‐sulfoximines is described that involves the use of diaryliodonium salts in aqueous polyethylene glycol‐400 and copper(I) bromide as catalyst at room temperature. The high yields of the products and simple work‐up are the highlights of the protocol.
