Nano ‐Zn[2‐boromophenylsalicylaldiminemethylpyranopyrazole]Cl2 as a novel nanostructured Schiff base complex and catalyst for the synthesis of pyrano[2,3‐d]pyrimidinedione derivatives

Nano ‐[Zn‐2BSMP]Cl2), as a novel nanostructured Schiff base complex, was prepared, characterized and successfullyused as an effective catalyst for the preparation of some pyrano[2,3 ‐d]pyrimidine dione derivatives. Nano ‐Zn[2‐boromophenylsalicylaldiminemethylpyranopyrazole]Cl2 (nano ‐[Zn‐2BSMP]Cl2) as a novel nanostructured Schiff base complex was prepared and characterized using several techniques. Nano ‐[Zn‐2BSMP]Cl2 was used as an effective catalyst for the preparation of some pyrano[2,3 ‐d]pyrimidinedione derivatives by the multicomponent reaction of malononitrile, aryl aldehydes and barbituric acid derivatives. The novelty and efficiency of nano ‐[Zn‐2BSMP]Cl2 as a catalyst, in comparison with some other reported catalysts, for this synthetic transformation are the main features of this work.
