CF3O-CONTAINING ENAMINOKETONES AND THEIR UTILIZATION FOR THE PREPARATION OF CF3O-CONTAINING PYRAZOLES
摘要
The present invention pertains to novel enaminoketones containing a CF 3 O-group, novel pyrazole-derivatives containing a CF 3 O group as well as to a novel process for their preparation comprising aminoformylation of CF 3 O-ketones and cyclization of the obtained CF 3 O-enaminoketones with hydrazines to trifluoromethoxy pyrazoles.
