Gas-Phase Reactions of the Hydroperoxide and Peroxyformate Anions

摘要

The flowing afterglow technique has been used to study the reactions of HO2(-) and HCO3(-) in the gas phase. The hydroperoxide ion reacts slowly with CO to form HO(-), and oxidizes Co2, CS2, NO, SO2, CH3NCO, and CH3NCS in fast reactions to form CO3(-), CO2S(-), NO2(-), 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 of form the formate ion HCO2(-). It also forms HCO2(-) upon reaction with acetone and pivalaldehyde, perhaps by Baeyer-Villiger oxidation.
