13C NMR data for chlorine- or nitro-substituted azomethine dyes
The 13C NMR spectra of 1‐aryl‐substituted 3‐methyl‐2‐pyrazolin‐5‐ones and their azomethine dyes have been recorded and assigned. ortho‐Substituents (Cl and NO2) on the phenyl ring in the 1‐position of the pyrazoline moiety show a small influence on the chemical shift of the azomethine bond carbon at...
