ABSTRACT
Peroxocarbonate ions HCO and CO, which are formed in the H2O2/NH4HCO3/HO- system, react with 4-nitrophenyl diethyl phosphonate (I) through a nucleophilic mechanism with rate constants $$k_{HCO_4^ - } = 0.008$$ and $$k_{CO_4^{2 - } } = 0.13 L/mol \cdot s$$ . Comparison of these constants with the corresponding constants of other inorganic anions in their reaction with I in the framework of the Brï¿½nsted equation indicates that HCO and CO are typical a-nucleophiles.
