This review summarizes the latest discoveries in the field of C−H activation by copper monoxygenases and more particularly
by their bioinspired systems. This work first describes recent background on copper-containing enzymes along with
additional interpretations about the nature of the active copper-oxygen intermediates. It then focuses on relevant examples
of bioinorganic synthetic copper-oxygen intermediates according to their nuclearity (mono to polynuclear). This includes a
detailed description of the spectroscopic features of these adducts as well as their reactivity towards the oxidation of
recalcitrant Csp3 − H bonds. The last part is devoted to the significant expansion of heterogeneous catalytic systems based
on copper-oxygen cores (i.e. within zeolites frameworks)
