It has been shown by the (19)F NMR method that the relative polarities of nitrogen-element bonds in 2-(4-fluorophenyl)benzimidazole and its PhHg and Ph3PAu derivatives increase in the order N-H a bimolecular associative mechanism and that the N-H bond is substantially less reactive than the N-Hg and N-Au bonds, which have identical reactivities within the limits of sensitivity of the method used. - Keywords: bond polarity, (19)F NMR, exchange reactions, kinetics and mechanism, 2-(4-fluorophenyl)benzimidazole, PhHg and Ph3PAu derivatives
