Bimetallicnanoparticles, particularly those based on copper, have recently attracted a great deal of attention for the development of low cost and highlyactive catalysts due to the synergistic interaction between individual metal components. In this work, bimetallic Ag–Cu alloynanoparticles were explored as a highlyactive and reusable catalyst for the enamination of 1,3-dicarbonyls using diverse

Cyanuric chloride is shown to be an extremely efficient catalyst for the synthesis of beta-enaminoesters from beta-ketoesters under solvent-free conditions by grinding in a mortar with pestle at 25 degrees C. A short reaction time, an inexpensive and easily available catalyst, mild reaction conditions and excellent yields of the products are attractive features of this methodology.
