ABSTRACT

Depending on the solvent nature, N(N′)-(2-bromo-3-ethoxypropyl)-N′(N)-(trifluoromethylsulfonyl)ethaneimidamide exists in two tautomeric forms: RNH–C(Me)=NTf and RN=C(Me)–NHTf. The shift of the tautomeric equilibrium from the more stable RNH–C(Me)=NTf to the less stable RN=C(Me)–NHTf in the solution in dimethyl sulfoxide and trifluoroethanol was shown by IR and NMR spectroscopy.
