A porous crytalline metal-organic framework Fe3O(BPDC)3 was synthesized, and its properties were characterized by various techniques, including X-ray powder diffraction (PXRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen physisorption measurements. The Fe3O(BPDC)3 was used as an efficient catalyst for the oxidative coupling reaction of benzaldehyde and (E)-1-phenylethan-1-one O-acetyl oxime to form 2,4,6-triphenylpyridine as desired product. The reaction could proceed readily, with more than 83 % reaction yield being achieved after 360 min at 140 oC in the presence of 10 mol% Fe3O(BPDC)3) catalyst and Di-tert-butyl peroxide as an oxidant. This Fe-MOF exhibited higher activity than other MOFs and traditional homogeneous catalysts in the oxidative coupling reaction. The transformation could only proceed to obtain main product in the presence of Fe3O(BPDC)3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
