The present invention relates to novel alkoxy enones and enamino ketones, and to a novel process for preparation thereof. Alkoxy enones and enamino ketones are valuable intermediates for preparation of pyrazoles and anthranilamides, which can be used as insecticides.
The present invention relates to a process for preparing 1-aryl-substituted pyrazoles, comprising the reaction of alkoxy enones and enamino ketones with arylhydrazine derivatives to give 1-aryl-substituted dihydro-1H-pyrazoles, the further reaction thereof with elimination of water to give 1-aryl-substituted trihalomethylpyrazoles, and the further processing thereof.
