Abstract
Novel, efficient, and recyclable bifunctional catalysts bearing SiO 2-supported RuCl3 and iodoarene moieties were developed and used for environmentally benign oxidation of alcohols or alkylarenes at the benzylic position. These reactions in the presence of oxone as stoichiometric oxidant afforded the corresponding carbonyl compounds in high yields under mild conditions and convenient work-up. Furthermore, these SiO2-supported bifunctional catalysts can be recovered by simple filtration and directly reused.
