Abstract
Detailed analysis of the temperature-dependent 1H n.m.r. spectra of 5-acyl-10,11-dihydrodibenz[b,f]azepine (N-acyliminobibenzyl) derivatives suggests the occurrence of three conformational equilibria–rotation of the ethano-bridge section, rotation of the amide C–N bond, and inversion of the central seven-membered ring; ring inversion and amide rotation occur in a novel, concerted manner.Keywords
