Abstract

Cis-trans isomerism in pyrazolines and the application of n.m.r. spectroscopy in differentiating between such isomers is discussed. Theoretical calculations of chemical shifts for some cis- and trans-4,5-disubstituted 2-pyrazolines are in agreement with assignments based on chemical considerations.
