| Abstract: | Absorption and fluorescence spectra of benzimidazolone derivatives have indicated that N-ethyl-2-(3H)-benzimidazolone (MBOH) and N-methyl-N-ethyl-2-(3H)-benzimidazolone (DBOH) behave as keto derivatives, whereas the N-methyl-2-methoxybenzimidazole (BIOM) behaves as an enol derivative. In monocations of MBOH and DBOH and monoanion of MBOH, the structural reorganisation takes place so that these species acquire benzimidazole structure. In BIOM, the negative inductive effect of methoxy group predominates over the resonance effect, thus leading to the decrease in the pKa of protonation reaction. |
