CF3O-containing enaminoketones and their utilization for the preparation of CF3O-containing pyrazoles

摘要

The present invention pertains to novel enaminoketones containing a CF3O-group, novel pyrazole-derivatives containing a CF3O group as well as to a novel process for their preparation comprising aminoformylation of CF30-ketones and cyclization of the obtained CF30-enaminoketones with hydrazines to trifluoromethoxy pyrazoles.
