1H dynamic nuclear magnetic resonance study of hindered internal rotation inN-aroyl- andN-thioaroyl-N′- piperonylpiperazines
Autor: Dante Nardi, Ferdinando Taddei, Rois Benassi, Amedeo Leonardi
Publikováno v: Organic Magnetic Resonance. 15:25-28
The NMR variable temperature behaviour of N-aroyl- and N-thioaroyl-N′-piperonylpiperazines was investigated. The largest chemical shift separation between the exchanging methylene groups, and the highest energy barrier, is found for the thioamide c

Conformational analysis of hydrazones.1H dynamic nuclear magnetic resonance and solvent effects in aryl- and 2-furylaldehyde ethylaminoacetylhydrazones
Autor: Adriano Benedetti, Dante Nardi, Alberto Tajana, Ferdinando Taddei, Rois Benassi, Roberto Cappelletti
Publikováno v: Organic Magnetic Resonance. 20:26-30
Aryl- and 2-furylaldehyde ethylaminoacetylhydrazones were examined in different solvents and over a wide temperature range with 1H NMR in order to study their conformational properties. Nearly equal amounts of the E/Z isomers, relative to the CN bond
