Reactions of ground state oxygen

We will now discuss some very recent applications of the soft El ionization method for product detection in CMB experiments. We will first deal with two polyatomic reactions of ground state oxygen atoms with unsaturated hydrocarbons (acetylene and ethylene) these reactions are characterized by multiple reaction pathways and are of great relevance, besides being from a fundamental point of view, in combustion and atmospheric chemistry.

As mentioned earlier in the discussion of exciplex formation, electron transfer between an excited state species and a ground state molecule (Equation 2.8 and Equation 2.9) is frequently observed in the photochemistry of systems containing an electron donor-acceptor combination. As a result, a pair of radical ions is formed that react with oxygen but with different rates. The reaction of ground state oxygen with radical anions occurs rapidly and yields superoxide anion (Equation 2.16). The superoxide then adds to the radical cation forming D02 (Equation 2.17). When D is an olefin, D02 is a dioxetan that is liable to cleave to yield ketones as products.

Kinetic data on transfer reactions of ground state oxygen atoms have undergone considerable changes and reassessment since the last major reviews of this topic [133, 134].

This only occurs at rather high temperatures (230°). Yet another case is that of the reaction of ground state oxygen with tetrakis-dimethylamino-ethylene in which a dioxetan is implicated [70-72] (p. 119).
