| Abstract: | in this paper ~1H and ~(13)C NMR spectra of 10 derivatives of acetanilides are recorded.The assignments of ~1H and ~(13)C NMR spectra of these compounds were confirmed by spindecoupled. selective proton decoupled. proton off-resonance decoupled, DEPT and selectiveINEPT techniques. The restricted rotation about the carbon-nitrogen bonds of the amide groupof acetanilides has been investigated. It has been proposed that the molecular structure of ace-tanilides in solution can be described in terms of an equilibrium between E-and Z-form. Theeffect of various substituents on conformation is discussed. |
