liquid, 1-butyl-4-aza-1-azaniabicyclo[2.2.2]octane hydroxide, has been developed as a catalyst for a convenient and rapid method for the Michael addition of active methylene compounds to α , β -unsaturated carboxylic esters and nitriles. The method is very simple, and the yields are very high. The catalyst can be recycled several times without much loss of activity.
摘要已开发出基于dabco的碱性离子液体1-丁基-4-氮杂-1-氮杂双环[2.2.2]辛烷氢氧化物,作为一种方便快捷的方法,用于将活性亚甲基化合物迈克尔加成的方法,β-不饱和羧酸酯和腈。该方法非常简单,并且产率很高。催化剂可以循环使用几次而不会损失很多活性。
