Box 37491-13191. R. Iran Boshra Mirhosseini-Eshkevari Department of Chemistry, Qom Branch, Islamic Azad University, Qom, I. R. Iran Manzarbanoo Esnaashari Department of Chemistry, North Tehran Branch, Islamic Azad University, Tehran, I. R. Iran Journal Article 2019 07 03 Metal-organic frameworks have attracted considerable attention because of their unique properties and potential applications in diverse fields. In this research, an efficient and simple method has been reported for the preparation of chromeno[2,3-b]pyridine derivatives through the multi-component reactions of salicylaldehydes, thiols and malononitrile in the presence of NiCo2O4@Ni(BDC) nanocatalyst. In this approache, the products were obtained in short reaction times and excellent yields. Moreover, the synthesized compounds were characterized by IR, 1HNMR and 13CNMR spectroscopy analysis. Also, the catalyst was fully characterized by spectroscopic techniques including field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), fourier transform infrared spectrophotometry (FT-IR), X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM) and thermogravimetric analysis (TGA).
