摘要

Abstract A practical, efficient, and inexpensive method for the synthesis of 2-imidazoline from the reaction of nitriles with ethylenediamine or 1, 2-propanediamine using p-toluenesulfonic acid or pyridinium p-toluenesulfonate under reflux conditions is reported. This catalyst can be successfully applied for the chemoselective conversion of dicyanobenzenes to corresponding mono-and bis-imidazolines. The applications of these catalysts are ...
