Superoxide ions with alkanes

Reactions of 02 with Alkanes and Alkenes. When compared with 0, the superoxide ion is a much less reactive species. Since the 02 is thermally stable up to -175°C, stoichiometric reactions must be carried out at 175°C or lower temperatures (12). Methane is essentially unreactive with 02 at 175°C, and the reaction with ethylene and propane is slow. Essentially all of the 02 ions re-... [Pg.136]

Superoxide ion is not highly reactive towards hydrocarbons (i.e., lipids) and is readily removed from biological systems by superoxide dismutase, forming hydrogen peroxide and oxygen. However, the protonated superoxide ion or hydroperoxyl radical, HO, reacts with NADH and alkanes. Although such a reactive... [Pg.157]
