Reversible addition of water to 1-vinylbenzimidazole-2-carbaldehyde and the corresponding cation was studied by UV spectroscopy. The cation turned out to be more reactive (K+l = 1.2 l/mol) than the neutral molecule (K0l = 2.9 × 10-2 l/mol). The concentration constants of acid dissociation of the hydrated and nonhydrated cations in aqueous solution were estimated at K+l 1.2 × 103 and 4.8 × 104 l/mol, respectively. Alcohols add to 1-vinylbenzimidazole-2-carbaldehyde without a catalyst, and the addition is reversible.
