| 摘要 |
<p>The present invention relates to a method for producing 1-pyridyl-substituted pyrazoles, comprising the reaction of acetylene ketones with pyridyl hydrazine derivatives to form 1-pyridyl-substituted dihydro-1H-pyrazoles, for the subsequent reaction of said pyrazoles to form 1-pyridyl-substituted trihalogenmethyl pyrazoles by dehydration, and for the subsequent processing of said pyrazoles.</p> |
