Abstract

Nano zinc oxide (Nano-ZnO) was explored as a reusable catalyst for the enamination of 1, 3- dicarbonyls using diverse amines. To make the process environmentally viable, the reaction was carried out under solvent-free conditions and found to give good yield of desired products. The catalyst was characterized by various analytical techniques such as UV- spectroscopy, XRD, and TEM. The catalyst was found to be reusable up to four catalytic ...
