General description

Difluoroaceticacid is a monocarboxylic acid and an organofluorine compound. Difluoroaceticacid is easy-to-handle reagent, useful for obtaining difluoromethyl substituents. Difluoroacetic acid can be used asdifluoromethylating reagent for the direct C−H difluoromethylation ofheteroaromatic compounds.

Application

Used in the preparation of 2-difluoromethylbenzimidazoles, -oxazoles and -thiazoles from ortho-substituted anilines mediated by triphenylphoshine.

The biotransformation and the hepato- and nephrotoxicity of the mercapturic acids (N-acetyl-1-cysteine S-conjugates) of three structurally related 2,2-difluoroethylenes were investigated in vivo in the rat. All mercapturic acids appeared to cause nephrotoxicity, without any measureable effect on the liver. The
