Magnetic nanocatalyst for the synthesis of maleimide and phthalimide derivatives

An efficient and green protocol for the synthesis of N-aryl maleimide and phthalimide derivatives has been developed. The high efficiency of the catalyst was observed due to the homogeneous distribution of the nanoparticles. The catalyst was fully characterised by physicochemical methods such as IR spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction, dynamic light scattering (DLS), energy dispersive X-ray spectrum and zeta potential measurement techniques. The ease of separation of the catalyst from the reaction mixture and its high activity are eco-friendly attributes of this system.

Reaction of Diphenylcyclopropenone with Nitroketeneaminals. Synthesis of 6-Amino-2-pyridones and Their m-Chloroperbenzoic Acid Oxidation to 2,3-Diphenylmaleimides

Reaction of diphenylcyclopropenone wit nitroketeneaminals gave 6-amino-2-pyridones, wich were oxidized by m-chloroperbenzoic acid to 2,3-diphenylmaleimides.
