In sufficiently hindered aromatic amines the dynamic plane containing the rapidly inverting nitrogen atom is twisted with respect to the plane of the aromatic ring. 2 As a consequence, 1- naphthylamines, having different substituents at the N atom, give rise to a pair of enantiomeric conformers. At low temperatures the rate of exchange between these conformers is slow and in the case of derivatives containing prochiral probes3 (eg, ethyl or ...
