详细
A pyridinecarboxaldimine grafted to silica-coated magnetic nanoparticles was prepared. The structure and magnetic properties of the functionalized magnetic silica nanoparticles were identified by TEM, FT-IR, XRD, elemental analysis, and vibrating sample magnetometer (VSM). The supported pyridinecarboxaldimine as chelating ligand in combination with CuBr2 and 2,2,6,6-tetramethyl-1-piperadoxyl (TEMPO) exhibited efficient catalytic performance in the aerobic oxidation of primary alcohols to aldehydes. The functionalized magnetic silica nanoparticles could be easily recovered using an external magnetic field and reused for at least 6 times with low reduction in its performance in the aerobic oxidation of benzyl alcohol.
