PET cat. While the copper(II) tren ketoprofenate precatalyst 1 (see picture) is inactive at room temperature in methanol, it is quantitatively and rapidly reduced to its cuprous state upon light irradiation to provide a highly reactive click catalyst. By simply introducing air into the reaction medium the catalysis can be switched off and then switched on again by bubbling argon followed by irradiation
宠物猫。酮基丙酸铜(II)预催化剂1(参见图片)在室温下在甲醇中无活性,但在光照射下会定量迅速地还原成亚铜状态,从而提供高反应性的点击催化剂。通过简单地将空气引入反应介质中,可以关闭催化剂,然后通过鼓泡氩气然后辐照再次打开催化剂。
