Cupric superoxo-mediated intermolecular C-H activation chemistry

Abstract

The new cupric superoxo complex [LCu II(O 2 -)] +, which possesses particularly strong O-O and Cu-O bonding, is capable of intermolecular C-H activation of the NADH analogue 1-benzyl-1,4-dihydronicotinamide (BNAH). Kinetic studies indicated a first-order dependence on both the Cu complex and BNAH with a deuterium kinetic isotope effect (KIE) of 12.1, similar to that observed for certain copper monooxygenases. © 2011 American Chemical Society.
