E. Wyrzykiewicz et D. Prukala, NEW ISOMERIC N-SUBSTITUTED HYDRAZONES OF ORTHO, META AND PARA HYDROXYBENZALDEHYDES, Polish Journal of Chemistry, 72(4), 1998, pp. 694-702
27 unknown N-(E)-stilbenyloxyalkylcarbonyl- and -(E)-stilbenyloxyalkyl
carbonyl-aminoalkylcarbonyl- substituted hydrazones of ortho, meta and
para hydroxybenzaldehydes were prepared. Front H-1-NMR (in DMSO-d(6))
was established thai the N-substituted hydrazones occurred as E geome
trical isomers and cis/trans amide conformers.
