Substituierte Pyrazolid‐3‐on‐azomethinimine

Azomethineimines. V. 1H‐N.M.R. Spectra and Steric Properties of Arylsubstituted Pyrazolidone‐Azomethineimines From the results of 1H‐n.m.r.‐spectroscopic investigations we tried to draw conclusions regarding the steric properties of pyrazolidone‐azomethineimines 1a–k. The influence of aromatic systems on chemical shift of the methineproton of the 1,3‐dipolar centre was calculated using the ring current model. Without the twisted 9‐anthryl‐substituted compound 1f experimental results show a good correspondence to the values of chemical shift calculated for two of four possible isomeric structures.
