Alkane hydroxylation by m-CPBA catalyzed by Co(II)-complexes
Catalytic activities of the cobalt(II) complexes supported by tripodal N4-tetradentate ligands have been examined in the alkane hydroxylation reaction by m-CPBA (m-chloroperbenzoic acid). Detailed product analysis data have indicated that hydrogen atom abstraction (HAA) from the alkane substrates is a key step in the hydroxylation reaction, where not only the aroyloxy radical intermediate (ArC(O)O•; Ar = m-chlorophenyl)) derived from m-CPBA via O–O bond homolysis but also a Co–O• type intermediate is involved as a reactive oxidant. Significant effects of the supporting ligands and the metal ions (FeII, NiII, and CuII) support this mechanism.
