In this research article, we describe the Cu-promoted intramolecular hydroxylation of sp2 and sp3 C-H bonds using directing groups with varying denticity (bi-, tri- and tetradentate) and natural oxidants (O2 and H2O2). We found that bidentate directing groups, in combination with Cu and H2O2, led to high hydroxylation yields. On the other hand, tetradentate directing groups did not form the hydroxylation products. Our mechanistic investigations suggest that bidentate directing groups allow for generating reactive mononuclear copper(II) hydroperoxide intermediates while tetradentate systems form dinuclear Cu2O2 species that do not oxidize C-H bonds. Our findings might shed light on the reaction mechanism(s) by which Cu-dependent metalloenzymes such as particulate methane monooxygenase or lytic polysaccharide monooxygenase oxidize strong C-H bonds.
