Hydrogen exchange at ring carbon in pyrazolium cations

3 Hydrogen exchange at ring carbon in pyrazolium cations [Pg.40]

The relative acidity of protons of l-benzylpyrazole-2-oxide has been determined by exchange with deuterium oxide-tetradeuteriomethanol/potassium hydroxyde 92ACS1096 as a result 59% and 55% of exchange at H3 and H5 was measured. [Pg.40]
