NMR Spectra and structure of 1-vinylpyrazoles

  • 18 Accesses

Conclusions

A1H and13C NMR spectral analysis permitted evaluation of electronic and steric effects in 1-vinylpyrazoles. 5-Methyl-1-vinylpyrazoles have predominantly S-cis-N2 orientation, while 1-vinylpyrazoles without substituents at C5 are conformer mixtures.
