Water → (3-Trifluoromethoxyphenyl)oxoacetaldehyde

Participants

Reaction Steps

To a solution of 1-(3-(trifluoromethoxy)phenyl)ethanone (5.0 g, 24.6 mmol) dissolved in 1,4-dioxane (75 mL) and water (4 mL) was added SeO2 (4.38 g, 39.4 mmol) in one portion. The mixture was refluxed overnight. The mixture was filtered to remove the black precipitate. The filtrate was concentrated and purified by column chromatography (1:5 Ethyl Acetate/Pentane) to give 2-oxo-2-(3-(trifluoromethoxy)phenyl)acetaldehyde as a yellow oil (5.3 g, 98% yield).
