• 4-nitrophenyl diethyl phosphonate
• hydrogen peroxide
• peroxyhydrocarbonate ion
• peroxocarbonate ion
• nucleophilicity

Peroxocarbonate ions HCO(4)(-) and CO(4)(2-), which are formed in the H(2)O(2)/NH(4)HCO(3)/HO(-) system, react with 4-nitrophenyl diethyl phosphonate (I) through a nucleophilic mechanism with rate constants k(HCO4-) = 0.008 and k(CO42-) = 0.13 L/mol center dot s. Comparison of these constants with the corresponding constants of other inorganic anions in their reaction with I in the framework of the Bronsted equation indicates that HCO(4)(-) and CO(4)(2-) are typical alpha-nucleophiles.
