Abstract
Osmium tetroxide was immobilized onto an imidazolium-based polymer, poly(l-methylimidazoliummethyl styrene styrene)-surface grafted-PS (PS-sg-IM) resin. In order to characterize the polymer imidazolium-supported osmium-complex catalysts, Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray microanalysis (EDX), and inductively Coupled plasma-atomic emission spectroscopy (ICP-AES) experiments were carried out, and we verified that the formation of the osmium complex Occurred only on the surface of the polymer support. This polymer catalysts was used in the dihydroxylation of various olefins, revealed excellent catalytic activity, and Could be reused up to three times.
