Example text

For oximes 161/162/163f,i single-crystal X-ray analysis and detailed NMR spectroscopic investigations showed that these compounds are present as (Z)configured enaminopyrazol-3-ones 161 in the solid state and in DMSO-d6 solution. From the similarities of the chemical shifts, particularly in the 13C NMR spectra, and the results of NOE-difference experiments, pyrazol-3-ones 161/162/163a–e,g,h also exist mainly in this isomeric form. However, in some of these derivatives a second set of minor signals is seen in their NMR spectra.
