Abstract

3-(Benzoimidazol-2-yl)-2-phenylimino-2H-chromenes were synthesized. The protolytic equilibrium constants in 50% ethanol were determined. The correlations of the pK a values for the compounds in the ground and excited states and the PM3-calculated heats of formation with the σ+ constants of substituents were established. The nitrogen atom of the benzoimidazole fragment is the center of protonation in the studied compounds.
