    Tautomeric Equilibria in Solutions of 2-Phenacylbenzimidazoles by Agnieszka Skotnicka, Przemysław Czeleń, Ryszard Gawinecki

    Published 2019-01-01
    “…., 2-(1,3-dihydro-2H-benzo[d]imidazol-2-ylidene)-1-phenylethan-1-one, was thermodynamically most stable, the results of MP2 ab initio calculations reveal the following order of stability: ketimine > enolimine > enaminone (substituents do not affect this sequence). 13C CPMAS NMR spectral data reveal that in the crystalline state the enolimine tautomer O is predominant in the p-CH3 and p-NO2 substituted congeners.…”
