Abstract:
The present invention relates to a process for preparing 1-pyridyl-substituted pyrazoles, comprising the reaction of acetyleneketones with pyridylhydrazine derivatives to give 1-pyridyl-substituted dihydro-1H-pyrazoles, the further reaction thereof with elimination of water to give 1-pyridyl-substituted trihalomethylpyrazoles, and the further processing thereof.
