    • Abstract


      The conformational analyses of α-mono, α-di and α-trichloroacetanilides have been carried out using IR spectroscopy. α-Monochloro, dichloro and trichloroacetanilides were found to exist in only one conformation in CH2Cl2 and CHC13. The existence of all these anilides in single conformation is due to intramolecular H-bond formation between N−H and Cl.

      In CH3CN, the broadening of C–0 bands of monochloroacetanilides and their bifurcation in α-dichloroacetanilides indicated the existence of two rotamers due to the breaking of chelation by the solvent.
