Amidines are one of the strongest organic bases and find application where this property is needed, such as in phase transfer catalysis in the form of their substituted derivatives. Their use, however, has been hampered by their expensive nature due to only mediocre yields in their preparation. The present invention provides a process for the preparation of substituted amidines in essentially quantitative yields.
Amidines是最强的有机碱之一,适用于需要此特性的应用,例如在相转移催化中以其取代衍
生物的形式。然而,它们的使用受到昂贵的限制,因为制备过程中产量只是中等
水平。本发明提供了一种制备取代amidines的方法,其产率基本上是定量的。
