The diprototropic tatomerism of 4,6-diphenacylpyrimidine was studied by the 1H, 14N, and 17O NMR methods.Examination of the spectra under equilibrium conditions and also observation of the dynamics of the tautomerization during the dissolution of diphenacylpyrimidine in chloroform made it possible to establish the presence of five tautomers (KE, KK, KI, EE, and EI) and to determine their ratios.
