The Effect of Solvent on the Ligand Substitution Reactions of Aquacobalamin (Vitamin B12a)

The kinetics of the substitution of coordinated H2O in aquacobalamin (H2Ocbl+, vitamin B12a) by pyridine (py) were studied as a function of temperature in water and in 70% (v/v) ethanol-water at pH 7.0. Saturation kinetics is observed, in agreement with a dissociative interchange mechanism. The valu...
