Abstract
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 CF3O-ketones and cyclization of the obtained CF3O-enaminoketones with hydrazines to trifluoromethoxy pyrazoles.
