Conclusions
-
1.
α-Acetylpolyfluorinated β-keto, esters with two or more carbon atoms in the fluoro-alkyl radical were obtained by acylation of acetoacetic ester by fluorocarboxylic acid chlorides in the presence of magnesium ethylate in benzene.
-
2.
The α-acetylpolyfluorinated β-keto esters exist in deuterochloroform as a mixture of a keto and two enol forms of the “diketonic” and “β-(polyfluoroalkyl)keto ester” fragments.
-
3.
α-Acetylpolyfluorinated β-keto esters react with 2,4-bis-(V-methoxyphenyl)-2,4-dithioxo-1,3,2,4-dithiadiphosphetane to form 4-acetyl-5-polyfluoroalkyl-1,2-dithiolene-3-thiones.
