A series of ionic liquids with different cations and anions were synthesized and their performances for the silver catalyzed one-pot A3-coupling reactions were investigated. The selection showed that the combination of AgNO3 and ionic liquid [TMG][TFA] showed highest catalytic activity. This catalytic system was then utilized for the production a series of propargylamines with satisfactory isolated
合成了一系列具有不同阳离子和阴离子的
离子液体,研究了它们在
银催化的一锅A 3偶联反应中的性能。选择表明,AgNO 3的组合
离子液体[
TMG] [TFA]表现出最高的催化活性。然后将该催化体系用于生产具有令人满意的分离产率的一系列
炔丙基胺。该反应系统非常简单且易于进行,因为不需要惰性气体或任何其他附加溶剂,碱性添加剂。这也带来了以下后处理程序的便利以及催化系统的回收和再利用。认为
离子液体通过与底物或作为助催化剂和
配体的催化剂的相互作用而参与了催化过程。
