| Zusammenfassung: | Copyright (c) 2008 John Wiley & Sons, Ltd. The (1)H, (13)C, and (15)N NMR spectra of 5 exocyclic alkenes and 15 different ketimines obtained from cyclohexanone and derivatives using benzyl bromide and primary amines-are analyzed. Relative stereochemical and preferential conformations are determined by analyzing both the homonuclear coupling and the chemical shifts of the protons and carbon atoms in the aliphatic rings, which are directly related to the geometry of the double bond and the steric and electronic effects of the exocyclic group. In addition, the racemic mixture of the N-(4-methylcyclohexylidene)pyridine-3-amine derivative is resolved |
