Gas-phase reactions of the hydroperoxide and peroxyformate anions

Abstract
The flowing afterglow technique has been used to study the reactions of HO2and HC3 in the gas phase. The hydroperoxide ion reacts slowly with CO to form HO, and oxidizes CO2, OCS, CS2, NO, SO2, CH3NCO, and CH3NCS in fast reactions to form CO3, CO2S, COS2, NO2, SO3, CH3NCO2, and CH3NCOS, respectively. Reactions of HO2 with certain amides and esters provide synthetic routes for a number of interesting peracyl anions. One of these, the peroxyformate ion, HCO3, reacts with CO and NO in slow oxidation reactions to form the formate ion HCO2. It also forms HCO2 upon reaction with acetone and pivalaldehyde, perhaps by Baeyer–Villiger oxidation.
