Summary

From a mechanistic point of view, the direct use of O2 as oxidant has to meet two major problems. These are outlined below, followed by strategies for possible solutions. To this end, two representative case studies are discussed, illustrating the scope and limitations of gas-phase experiments. We omit experimental details and restrict ourselves to the fundamental requirements in the activation of O2 as deduced from model studies conducted with isolated species in the highly diluted gas phase, thus excluding complicating effects due to the presence of solvents, counter ions, aggregation, bulk phenomena etc.
