A simple and practical procedure is described for synthesis of 2-aryl dihydroperimidines. One-pot reaction of 1,8-diaminonaphthalene with a variety of aromatic aldehydes, in the presence of nano-copper Y zeolite as highly efficient catalyst, was performed in ethanol at room temperature. The CuY zeolite nanocatalyst was characterized by scanning electron microscopy (SEM). Novel compounds were characterized by spectroscopic and spectrometric analyses. This environmentally benign and clean synthetic procedure has several advantages, including the availability, safety, and reusability of the catalyst, high yields, short reaction times, and easy and rapid isolation of the product.
