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 the 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,适用于需要这种性质的领域,例如在相转移催化中,以其取代衍
生物的形式存在。然而,它们的使用受到了昂贵的制备成本的限制,因为其产率仅为中等
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。
