Reaction Steps

Combine 5,5,5-trifluoropentanal (2.01 g, 14.35 mmol), 1,4-dioxane (10 mL), selenium dioxide (1.62 g, 1.0 eq), water (0.51 mL), and acetic acid (0.69 mL). Heat the mixture at 90° C. and stir overnight. Allow the reaction mixture to cool to room temperature. Filter, wash the solids with dioxane. Combine the filtrate and washings to give 5,5,5-trifluoro-2-oxopentanal (2.21 g, 100%). GCMS m/z=154.
