Title:
Those use for manufacture of CF3O-content Enamino ketone and CF3O-content Pyrazole
Document Type and Number:
Japanese Patent JP6212056
Kind Code:
B2
Abstract:
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.
