The preferred conformations of the enamine 1 and the hydrazones 3, 4, and 5 (prepared for the first time) were determined by 1H n.m.r. spectroscopy. The amino groups of these compounds are coplanar with the cyclohexadienone ring. The spectra at various temperatures yield information concerning the barriers of intramolecular motions at the C=CH–N̄ and C=N̄–N̄ system (Table 2). The low barrier to ...
