Molecular oxygen is a much desired oxidant for the functionalization of organic compounds, as it is readily available and inexpensive. Thus, synthetic and catalytic methods that use O2 offer in principle significant economic and environmental advantages. The development of selective methods, however, remains a challenging task. In this context, organometallic O2 reactivity is an area of growing interest, because it offers insights into possible oxygenation mechanisms and provides a basis for the design and development of new catalytic methods. In this talk, I will present a project from my research group that is aimed at the activation of O2 and other small molecules by low-valent Ir alkene complexes. We investigate the mechanisms of such reactions and the properties of intermediates with the goal of developing synthetic cycles of small-molecule activation and atom transfer. This work has led to the identification of (alkene)peroxo intermediates, where both the oxidant and the substrate are bound to the metal center. Such species are intriguing, because they have been proposed as key intermediates in stoichiometric and catalytic alkene oxygenation.
