Overview

Difluoroacetic acid is a monocarboxylic acid and an organofluorine compound. It is an easy-to-handle reagent used to prepare difluoromethyl substituents. Difluoroacetic acid can be used as a difluoromethylating agent for the direct C-H difluoromethylation of heterocyclic compounds. It has a strong odor. It is miscible with ethanol, ether, benzene, etc. It is used in the preparation of 2-difluoromethylbenzimidazole, oxazole, and thiazole from ortho-substituted anilines mediated by triphenylphosphine.
