| | Difluoroacetic acid Usage And Synthesis |
| Chemical Properties | clear colorless to light brown liquid | | Uses | Used in the preparation of 2-difluoromethylbenzimidazoles, -oxazoles and -thiazoles from ortho-substituted anilines mediated by triphenylphoshine. | | Definition | ChEBI: A monocarboxylic acid that is acetic acid in which two of the methyl hydrogens are substituted by fluorines. | | Flammability and Explosibility | Non flammable | | Purification Methods | Purify the acid by distilling over P2O5. The acid chloride is a fuming liquid b 25o/atm, and the amide has b 108.6o/35mm, m 52o (from *C6H6), and the anilide has b 90o/1mm, 114o/5mm, m 58o [Henne & Pelley J Am Chem Soc 74 1426 1952, Coffman et al.
