Preparation and characterization of Pd supported on 5-carboxyoxindole functionalized cell@Fe(3)O(4) nanoparticles as a novel magnetic catalyst for the Heck reaction

Pd supported on 5-carboxyoxindole functionalized cell@Fe(3)O(4) nanoparticles (Pd@CAI@cell@Fe(3)O(4)), a new magnetic nanocatalyst, was prepared and characterized using inductively coupled plasma atomic emission spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and energy-dispersive X-ray spectroscopy techniques. The synthesized nanocatalyst (Pd@CAI@cell@Fe(3)O(4)) was employed for Heck-type arylation of different substituted maleimides with iodoarenes in good to excellent yields. This green catalyst was easily recovered and reused several times with no substantial loss of activity, providing a clean and efficient synthetic procedure with excellent yield and reduced time.
