The conformational preference of 2, 2′-bisanilides was investigated by variable- temperature NMR spectroscopy, NMR titration and diffusion experiments, IR spectroscopy, computational analysis, and X-ray crystallography. The formation of a conformation having the two amide moieties linked by an intramolecular hydrogen bond was detected at low temperatures. The interconversion kinetics of the two conformational species of bisanilide ...
