What the study found
The study found that diketoesters can be obtained by reacting dialkyl esters of perfluoroadipic and perfluoropimelic acids with alkyl ketones. It also found that, in reactions of dimethyl perfluorododecanedioate with alkyl ketones, using THF (tetrahydrofuran) increases the yield of tetraketones.
Why the authors say this matters
The authors indicate that these findings are relevant for studying how polyfluorinated tetraketones are synthesized. They also conclude that calculations of possible reaction stages can help discuss details of the reaction mechanism.
What the researchers tested
The researchers studied reactions between dialkyl esters of perfluoroadipic and perfluoropimelic acids and alkyl ketones, and they examined the synthesis of polyfluorinated tetraketones from dimethyl perfluorododecanedioate and alkyl ketones. They also used non-empirical MP2/6-31G* calculations to analyze possible stages of the process.
What worked and what didn't
The formation of diketoesters from the perfluorinated diester precursors and alkyl ketones was achieved. In the tetraketone synthesis, THF increased the yield. The abstract does not report any conditions or approaches that failed.
What to keep in mind
The available summary does not give quantitative yields, reaction conditions beyond THF, or detailed experimental comparisons. It also does not describe limitations of the study beyond noting that the mechanism was discussed using computational results.
