Abstract
Four MIL metal organic framework materials with large surface area and high stability were utilized as heterogeneous catalysts in the selective oxidation of styrene with tert-butylhydroperoxide (70% aqueous) as an oxidant in acetonitrile. Mn-MIL-100 exhibits excellent styrene conversion (89%) and benzaldehyde selectivity (85%) under optimized conditions. Furthermore, Mn-MIL-100 displays superior catalytic activity in the selective oxidation of aryl-olefins and is reused at least three times without significant deactivation. It appears that this specific material would open up a new pathway for MOFs towards the selective catalytic oxidation of aryl-olefins to the corresponding aldehydes.
