Abstract The metal-oxo functionality plays a pivotal role in bio-inspired catalysis. Our understanding of the chemical reactivity of this remarkable motif found in various biological contexts has evolved over the years from a classical and conventional picture of a simple metal-oxo functionality to the recognition that the oxygen is better represented as radicaloid, metal-bound oxyl, or even a metal-bound oxene functionality. The distinction of these different resonance structures is useful, as it allows for rationally understanding the chemical reactions that these functional groups can promote. In particular for late transition metals, additional complications arise from the concept of the oxo wall, which stipulates that terminal metal-oxo compounds should not exist beyond d5-centers in tetragonal structures. In this talk, I will review some of the reactivities that we studied in the recent past to relate the electronic structure of Metal-Oxygen framework in various oxidation states to it functional role during catalysis.
