A bimetallic metal–organic framework material, which was generated by bridging iron (III) cations and nickel (II) cations with 1,4-Benzenedicarboxylic anions (Fe2Ni-BDC), was synthesized by a solvothermal approach using nickel (II) nitrate hexahydrate and iron (III) chloride hexahydrate as the mixed metal source and 1,4-Benzenedicarboxylic acid (H2BDC) as the organic ligand source. The structure of samples was determined by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, and nitrogen physisorption measurements. The catalytic activity and recyclability of the Fe2Ni-BDC catalyst for the Michael addition amidation reaction of 2-aminopyridine and nitroolefins were estimated. The results illustrated that the Fe2Ni-BDC catalyst demonstrated good efficiency in the reaction under optimal conditions. Based on these results, a reaction mechanism was proposed. When the molar ratio of 2-aminopyridine and trans-β-nitrostyrene was 1:1, and the solvent was dichloromethane, the isolated yield of pyridyl benzamide reached 82%; at 80 °C over 24 h. The catalyst can be reused without a substantial reduction in catalytic activity with 77% yield after six times of reuse.

Metal-organic framework MIL-53(Al) was synthesized by a solvothermal method using aluminium nitrate as the aluminium source and 1,4- benzenedicarboxylic acid (H2BDC) as the organic ligand. The structure of MIL-53(Al) was characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The catalytic activity and recyclability of MIL-53(Al) catalyst were evaluated based on the Paal-Knorr reaction between aniline and acetonylacetone. The reaction conditions were optimized and the results showed that the MIL-53(Al) catalyst exhibited good catalytic activity and recyclability based on the PaalKnorr reaction. With the molar ratio of MIL-53(Al) catalyst of 10 mol %, the molar ratio of aniline and acetonylacetone of 1:1.2, and without solvents, the conversion of aniline could reach 100 % and the selectivity of 2,5-dimethyl-1-phenyl-1H-pyrrole has high yield (95-100 %) after 2 hours by ultrasound activation. The MIL-53(Al) catalyst can be reused five times without significant degradation in the catalytic activity.

AbstractA one-pot three component reaction of benzaldehydes, 1H-tetrazole-5-amine, and 3-cyanoacetyl indole in the presence of a new hexamethylenetetramine-based ionic liquid/MIL-101(Cr) metal–organic framework as a recyclable catalyst was explored. This novel catalyst, which was fully characterized by XRD, FE-SEM, EDX, FT-IR, TGA, BET, and TEM exhibited outstanding catalytic activity for the preparation of a range of pharmaceutically important tetrazolo[1,5-a]pyrimidine-6-carbonitriles with good to excellent yields in short reaction time.
