Reactions of trifluoroamine oxide:: a new method for selective fluorination of 1,3-diketones and β-ketoesters

Fluorination of 1,3-diketones and beta-ketoesters with trifluoroamine oxide in the presence of tetrabutylammonium hydroxide (TBAH) provides a one step route to mono- and difluoro-products selectively fluorinated at the alpha-position in good yields.
