| Abstract [eng] |
Dependent on the reaction conditions, 1-phenylpyrazol-3-ol and bromine give either 4-bromo-1-phenylpyrazol-3-ol (2a) or 4-bromo-1-(4-bromophenyl)pyrazol-3-ol (2b). Treatment of 2a or 2b with refluxing acetic anhydride leads to the corresponding O-acetyl derivatives 3a and 3b, respectively. Detailed spectroscopic data (1H NMR, 13C NMR, 15N NMR, MS, IR) for 2b, 3a and 3b are presented. |
