Cobalt Schiff Base Complex Catalyzed Dehydrogenation of Amines with t-Butyl Hydroperoxide

Article abstract of DOI:10.1246/cl.1991.1093

Cobalt Schiff base complex catalyzed oxidation of secondary aromatic amines with t-butyl hydroperoxide resulted selectively in dehydrogenation to give the corresponding imines.Proposed mechanism involves electron transfer from the nitrogen atom in the substrate to t-butyloxyl or t-butylperoxyl radical produced in situ from a t-butylperoxocobalt(III) complex intermediate.
