| titleOfInvention | A kind of method of synthesizing fluoro Fluorenone compounds |
| abstract | The invention discloses a kind of method of synthesizing fluoro Fluorenone compounds, it is characterized in that described method is: with the adjacent tertiary butyl acetenyl chalcone compounds shown in formula 1 as raw material, in organic solvent, under the effect of copper catalyst and fluorine oxidiser, 0.5～6h, the fluoro Fluorenone compounds shown in the isolated and purified prepared formula 2 of gained reactant liquor is reacted at a temperature of 25～60 DEG C.Reactions steps of the present invention is simple, and substrate is popular good, the advantages such as reaction condition is gentle, safety and environmental protection；It directly with the non-aromatic chalcone of various free-florides as raw material, with cheap copper as catalyst, is a kind of variation route synthesizing the various fluoro Fluorenone compounds containing substituent. |
