| titleOfInvention | High purity preparation of fluorinated 1,3-dicarbonyls using BDM (bis-fluoroxydifluoromethane) |
| abstract | A process for providing an α-fluorinated-β-dicarbonyl includes electrophilically fluorinating a β-dicarbonyl with bis-fluoroxydifluoromethane in the presence of an acid to provide the α-monofluorinated-β-dicarbonyl. The acid is preferably hydrofluoric acid. Preferred β-dicarbonyls include methyl-3-oxopentanoate and ethyl-4,4,4-trifluoroacetoacetate. The process can limit radical impurity byproducts to no more than 4% in some cases, and less than 0.5% in other cases. Theoretical yields of 95% α-monofluorinated-β-dicarbonyl are possible in some cases. |
