Abstract
Conformations and configurations were assigned to several aliphatic N-methylhydrazones from analysis of their 60-Mc NMR spectra. Interpretation of the vicinal spin-spin coupling constants, J H 1Hα , of the syn isomers (N-methylamino cis to hydrogen) of the aldehyde N-methylhydrazones in terms of rotamers I and II gave ΔH° values that are similar to those found in hydrazones, oximes, and oxime O-methyl ethers. The anisotropic effects of the CN double bond, the association between solute and solvent, several aspects of the chemical shifts, and other problems related to configurational isomerism about the CN double bond are discussed.
