Investigations UiO-66-NH-EtNH2 ascatalyst for the preparation of enoneα,β-enone

Metal-organic frameworks (MOFs) are crystalline porous materials [1,2]. MOFs are promising materials for various technological applications, including gas storage, separation, drug delivery, and chemical sensing. In recent years, MOFs have been been used as heterogeneous catalysts [3,4].In this study, we prepared UiO-66-NH2 (Fig. 1) the using a simpler method and was evaluated as heterogeneou catalyst for reaction between benzaldehyde and malonitrile.The obtained material has been characterized by XRD, FT-IR, TGA, SEM and BET. The effect of various reaction parameters such as type of the solvent and amount of the catalyst were studied. The catalyst shows excellent performance in the reaction ofphenols and aryl halides with good to excellent yield.
