Lane, Thomas J. published the artcileMetal binding of the benzimidazoles, Related Products of imidazoles-derivatives, the publication is Journal of the American Chemical Society (1960), 2994-7, database is CAplus.
The acid dissociation constants were determined potentiometrically for benzimidazole (I), 2-methylbenzimidazole (II), and 2-ethyl-benzimidazole in solutions of ionic strength 0.16M (NaNO3) at 4 ± 1, 25 ± 0.1, and 35 ± 0.1°. The enthalpy changes ΔH0 were 8.7, 9.8, and 9.3 kcal./mole for the resp. compounds Formation constants were determined for Cu(II) with I by the Bjerrum potentiometric method in solutions of the same ionic strength at the 3 temperatures An upper limit was found for the value of the formation constant of Cu(II) with II at 4°. The formation constants for Cd with I and II were determined by a polarographic method in 50% aqueous EtOH at 25 ± 0.1°. The benzene portion of I appears to hinder coördination with Cu(II). Formation constants for Cu(II) with 2-(hydroxymethyl)benzimidazole and 1-methyl-2-(hydroxymethyl)benzimidazole show that the unsaturated N is the active site in the substituted I.
