es via four-component reaction of aromatic aldehydes, acetophenone derivatives, malononitrile and ammonium acetate is described. The reactions were done in water as solvent using cellulose sulfuric acid as catalyst. This simple protocol offer advantages such as shorter reaction times, simple work-up procedure, excellent yields and catalyst recovery.
描述了一种通过芳族醛,苯乙酮衍生物,丙二腈和乙酸铵的四组分反应合成2-氨基-4,6-二苯基烟腈的简便方法。反应以纤维素硫酸为催化剂,在水为溶剂中进行。这种简单的方案具有诸如缩短反应时间,简化后处理程序,优异的收率和催化剂回收率等优点。
