Reaction Conditions

Reaction Steps

A sealable vial was charged with triethylorthoformate (1.07 mL, 6.41 mmol), acetic anhydride (3.22 mL, 34.2 mmol) and ethyl 4,4,5,5,5-pentafluoro-3-oxopentanoate (0.747 mL, 4.27 mmol), and the resulting mixture was capped and stirred at 135° C. After 2 h, the reaction mixture was allowed to cool to room temperature, and the volatiles were removed in vacuo to provide the title compound as a mixture of olefin isomers, which was used without further purification.
