Brønsted acidic ionic liquid, triphenyl(propyl-3-sulphonyl)phosphonium toluenesulfonate, has been used as an efficient and reusable catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free conditions in excellent yields.
布朗斯台德酸性离子液体三苯基(丙基-3-磺酰基)phosph磺酸甲苯磺酸盐已被用作一锅合成2,4,5-三取代和1,2,4,5-四取代的咪唑的有效且可重复使用的催化剂在无溶剂条件下,收率极高。
