ABSTRACT:
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.
