Özet

The gas and aqueous phase geometries, hats of formation, entropies, dipole moments, proton affinities and methyl cation affinities of some furylpyridines and thienylpyridines have been studied to predict their basicity and pK(a) values, using semiempirical AM1, PM3 and MNDO quantum-chemical calculations at SCF level in gas and aqueous phases, with full geometry optimisation.
