Difluoroacetaldehyde
Difluoroacetaldehyde is an organofluorine compound with the chemical formula CHF2CHO. It is a volatile liquid at room temperature. It is a highly reactive aldehyde due to the electron-withdrawing effect of the two fluorine atoms. This makes the carbonyl carbon more electrophilic. Difluoroacetaldehyde exists in equilibrium with its hydrate, difluoroacetaldehyde hydrate, CHF2CH(OH)2, which is more stable. The hydrate can be prepared from the reaction of chloral hydrate with potassium fluoride. The anhydrous form is more difficult to isolate due to its reactivity and tendency to polymerize. Difluoroacetaldehyde has found some applications as a reagent in organic synthesis, particularly in reactions involving nucleophilic addition to the carbonyl group. Its unique electronic properties can lead to different reaction pathways and products compared to non-fluorinated aldehydes. Research into its specific chemical behavior and potential uses is ongoing. It is considered an irritant and should be handled with appropriate safety precautions.
