| Abstract: | Catalytic oxidation of benzene under mild
conditions is one of the most challenging reactions in synthetic chemistry. In
order to develop a hydroxylation catalyst for benzene, we have designed and synthesized
new copper(II) complexes with the bidentate ligand
bis(1,4,5-trimethyl-2-imidazolyl)methane (Me6bim), [Cu(Me6bim)X2]
(X = Cl, Br). This ligand provides a reaction space which can be easily accessed
by exogenous substrates and has an imidazole group, which is a typical ligand
of metalloenzymes. These complexes exhibit catalytic oxidation of benzene in
the presence of excess H2O2 at room temperature in
aqueous MeCN solution to yield phenol and 1,4-benzoquinone. |
