摘要: The structures of three azines derived from 2-formylimidazole, 4(5)-formylimidazole, and 4(5)-formyl-5(4)-methylimidazole have been determined in solution the solid state. Density Functional Theory (DFT) Polarizable Continuum Model (PCM) calculations (geometries, energies, chemical shifts), NMR [solution cross polarization magic-angle spinning (CPMAS)], X-ray crystallography [azine 4(5)-formylimidazole] used. configuration around central C = N bonds has some insights about prototropic tautomerism conformation gained.
