N2 - The tautomerism of the aliphatic MeC(NH2)NOH and the aromatic PhC(NH2)NOH amidoximes in protic (H2O, MeOH) and aprotic (Me2CO, Me2SO, and CHCl3) solvents was studied by density functional theory calculations at the M06-2X/6-311+G(d,p) level of theory. In both types of solutions, these species exist in 3 tautomeric forms, viz, (Z)- or (E)-amidoximes, and (Z)-aminonitrone. The (Z)-form is the dominant, and energy gap between the (Z)- and (E)-tautomers of the amidoximes slightly depends on the nature of a solvent and significantly higher than that for other oxime species. For the amidoximes, the zwitterionic (Z)-aminonitrone form is stabilized by protic solvents. The oxime-nitrone energy gap is reduced by electron-donor substituents at the oxime moiety at different types of oxime species.
