Abstract
Triethylammonium hydrogen sulfate [Et3NH][HSO4]) has been used as an efficient acidic ionic liquid catalyst for the preparation of 1,5-diaryl-3-(arylamino)-1H-pyrrol-2(5H)-ones at room temperature. The present methodology offers the advantages of good yields, a simple procedure, shorter reaction times and mild condition. The products were purified without resorting to chromatography.
