Henry Reaction Catalyzed by Mesoprous Molecular Sieve MCM-41 Supported Triazole-based Schiff Base and Cobalt Acetate

The catalytic properties of 2-phenyl-2H-1,2,3-triazole-4-carbaldehyde functionalized mesoporous molecular sieve MCM-41 materials and cobalt acetate in the nitroaldol(Henry) reaction are reported. The catalyst was characterized by methods of Fourier transform infrared spectroscopy(FT-IR) and X-ray diffraction(XRD). The reaction conditions such as metal salts, different solvents were investigated at room temperature. And the catalyst can be separated by simple filtration and reused for several times without much loss in performance with the yield up to 80.5%.
