反応手順

0.22 g (9.7 mmol) of sodium was dissolved in 50 ml of ethanol, 2 g (8.1 mmol) of 1-butoxy-4,4,5,5,5-pentafluoropent-1-en-3-one and 0.86 g (8.1 mmol) malonamide were added and the mixture was heated under reflux for 7 h. The mixture was concentrated, and 1N hydrochloric acid was added. The resulting precipitate was filtered off with suction and dried. This gave 1.9 g (94% of theory) of a yellow powder.
