Manganese salophen complex supported on magneticnanoparticles as an efficient, selective and recyclable catalyst forepoxidation of alkenes

A magnetically recoverable catalyst consisting of Mn (III) salophen complex was prepared. Thesynthesized catalyst was characterized by X-ray powder diffraction (XRD), transmission electron microscopy(TEM), vibrating sample magnetometry (VSM), inductively coupled plasma atomic emission spectroscopy (ICPAES)and Fourier transform infrared (FT-IR). The immobilized catalyst was shown to be an efficientheterogeneous catalyst for the epoxidation of various alkenes using hydrogen peroxide (H ۲O۲) as oxidant. Thecatalyst could be easily and efficiently isolated from the final product solution by magnetic decantation and bereused for ۵ consecutive reactions without showing any significant activity degradation
