Rate constants and activation parameters have been determined for the reactions of the aromatic amines N-methylimidazole and N-methylbenzimidazole with methyl iodide in acetonitrile-methanol.The enthalpies of solution have also been determined for the relevant species in the same solvent mixtures.Activation enthalpies in acetonitrile and specific interaction enthalpies between the amine and methanol show a linear correlation with pKa values determined in water only over a narrowly defined type of structure.However, transition-state indices for the two reactions defined in terms of physical interaction energy, αphys and βphys, show the behaviour anticipated by analogy with reactions of pyridine derivatives. (i.e., family-independent character).
