Difluoroacetic acid Chemical Properties,Usage,Production
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.
