A Spectral Study of Intermolecular Hydrogen Bonding for N-methylaniline or Diphenylamine with some Proton Acceptors
Abstract:
Infared Spectra of (N-methylaniline or diphenylamine + one of aprotic sol vents+CCL_4) have been measured at 298.15 K. The results show that stretching frequen cies v_(NH) of the associated complex A—H…B depend on the proton-accepting abilities of B, and the frequency shifts show a nearly linear dependence on electron donor num ber (DN) and also on nucleophilicity parameter (B~o). Equilibrium constants of some AB cross-associated complexes have been estimated from IR data. The equilibrium constant values show that diphenylamine as a proton donor is stronger than N-methylaniline. Morever, the related conclusions have been briefly discussed in terms of molecular structure and interactions between unlike molecules.
