In this research, nano magnetic sulfated zirconia was prepared through a green and facile method and acted as a novel, heterogeneous, efficient nano-catalyst for the one-pot three component synthesis of α-aminonitrile derivatives.
Various aryl aldehydes underwent prompt one pot conversion into the corresponding azomethines in high yields by reacting with hydroxylamine hydrochloride supported on melamine formaldehyde under microwave irradiation.
