NMR Investigation of Alkaline Derivatives of 1,3-Dicarbonyl Compounds
Configuration stability and stereodynamics of different ionic particles in alcaline derivatives of 1,3-dicarbonyl compounds’ solutions were investigated by 1H and 13C spectroscopy and conductometry. In aprotic dipolar solvents and methanol free ions were proved to give the main contribution to the “trans” (E,Z and E,E) form. E,Z⇄E,E transition was shown to be a rotation in a “free” enolate-anion.
