Recyclable silica-supported iodoarene-RuCl sub(3 bifunctional catalysts for oxidation of alcohols and alkylarenes)

Novel, efficient, and recyclable bifunctional catalysts bearing SiO sub(2-supported RuCl) sub(3) 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 SiO sub(2-supported bifunctional catalysts can be recovered by simple filtration and directly reused.)
