1,1,1-Trifluoroacetylacetone

1,1,1-Trifluoroacetylacetone is the organofluorine compound with the formula CF3C(O)CH2C(O)CH3.

Like other 1,3-diketones, it is used as a precursor to heterocycles, e.g. pyrazoles, and metal chelates.

[1] It is prepared by condensation of esters of trifluoroacetic acid with acetone.

[2] According to an analysis by proton NMR spectroscopy, the compound exists predominantly (97% at 33 °C, neat) as the enol.

For comparison under the same conditions, the percent enol for acetylacetone and hexafluoroacetylacetone are 85 and 100%, respectively.
