Figure Abstract

Caption

Dioxygen activation by mononuclear copper in biological and synthetic systems may generate various copper-oxygen intermediates including [CuO2]+, [CuOOH]+, [CuO]+, [CuOH]2+. All these species are able to perform O-H activation, while only [CuO]+ and [CuOH]2+ are reactive for C-H activation. However, the formation of [CuOH]2+ is highly unfavorable in monooxygenases, leaving [CuO]+ as the only active intermediate responsible for C-H activation in monooxygenases. These insights can provide consistent understanding on reactivities of various copper-oxygen active species in biological and synthetic systems.
