Innovative cyclohexanone synthesis via transfer hydrogenation of phenol and cyclohexanol

Novel and promising approach for cyclohexanone synthesis via the comproportionation reaction of cyclohexanol and phenol over conventional Raney nickel and Ni/Al₂O₃ was examined for the first time. Ni/Al₂O₃ catalyst was prepared by coprecipitation in supercritical CO₂.
