A simple and versatile method for the modification of a metal-organic framework (NH2-MIL53(Al)) in a step-wise manner was reported. To characterize the synthesized nanostructured catalyst, a variety of spectroscopic and microscopic techniques including FT-IR, XRD, BET, TEM, FE-SEM, EDX, EDX-mapping, TGA, XPS, VSM, ICP-OES and CHN have been employed. Fe3O4@AMCA-MIL53(Al)-NH2-CoII NPs, which benefit from small nanocrystalline size (10-30 nm, according to the XRD and TEM data) in combination with the coexistence of magnetic nanoparticles, a metal-organic framework, and cobalt species, were found to be an excellent environment catalyst to promote the C-N and C-S cross coupling reactions. A wide range of functional substrates including electron-withdrawing and electron-donating aryl halides RC6H4X (R = H, 2-O2N, 3-H3C, 4-CHO, etc.; X = I, Br, Cl) underwent the coupling reaction with aromatic/heteroaromatic/benzylic and aliphatic amines R1NH2 (R1 = Bu, 2-pyridy, 2-chlorobenzyl, 4-bromophenyl, etc.) and sulfides R2NH2 (R2 = 3-sulfanylpropyl, 4-nitrophenyl, 2-hydroxyethyl, etc.). The results demonstrated that the yields of the target products RC6H4NHR1/RC6H4SHR2 were good to excellent and the catalyst can be recycled for at least seven recycling runs without a discernible decrease in its catalytic activity. Furthermore, the heterogeneity studies (such as hot filtration and poisoning tests) efficiently confirmed that the as-synthesized nanostructured catalyst is heterogeneous and completely stable under the reaction conditions. This study inspires more interest in designing novel catalysts based on using low-cost metal ions (such as cobalt) in the field of cross coupling reactions.
