摘要:
In this work, post-synthesis modification of Fe3O4/IRMOF-3 nanocomposite with chlorosulfonic acid groups afforded sulfamic acid-functionalized magnetic metal-organic frameworks (Fe3O4/IRMOF-3/SO3H). Functionalization was followed through FT-IR, XRD, TGA, BET, FESEM/EDS and elemental analysis. The catalytic efficiency of the as-prepared nanocomposite was evaluated through one-pot pseudo four-component reaction of secondary amines, malononitrile, and salicylaldehyde in EtOH under mild conditions. The magnetic tendency of the functionalized IRMOF-3 enabled simple decantation from the reaction mixture with use of an external magnetic field, with subsequent catalyst reuse for at least five times without significant loss of catalytic efficiency.
