| 发明名称 | CF<sub>3</sub>O-containing enaminoketones and their utilization for the preparation of CF<sub>3</sub>O-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 CF3O-ketones and cyclization of the obtained CF3O-enaminoketones with hydrazines to trifluoromethoxy pyrazoles. | ||

| 主权项 | 1. Process for preparing an enaminoketone of formula Iwherein Rl is C5-C10 aryl, optionally substituted by 1 to 5 halogen atoms, or C5-C10 aryl exhibiting one, two or more heteroatoms selected from oxygen and nitrogen, and R2 and R3 are independently C1-C6 alkyl, C5-C10 aryl, C5-C10 aryl exhibiting one, two or more heteroatoms selected from oxygen and nitrogen, or form together a 5 or 7 membered ring which comprises (A) reacting a CF3O-ketone of the formula II wherein Rl is as defined above with an aminoformylation reagent. | ||
