Sažetak
The question of the stability of the bicyclic form of AA is addressed by several theoretical methods varying in the level of sophistication. Both semi- empirical and ab initio approaches indicate that the bicyclic form is somewhat more stable than the 2,3-enediol tautomer (7). However, the tautomer I has a significantly higher dipole moment indicating that it gains additionally in stability if dissolved in polar solvents due to strong electrostatic solvent-solute interactions.
