Abstract

Nano-Zn[4-nitrophenyl-salicylaldimine-pyranopyrimidinedione]Cl2 {Nano-[Zn-4NSP]Cl2}, as a new Schiff base complex and heterogeneous catalyst, was prepared and fully characterized by different analyses. Nano-[Zn-4NSP]Cl2 was applied as an efficient catalyst for the synthesis of some 5-amino-1H-pyrazole-4-carbonitrile derivatives.
