General description
2,2-Difluoro-2-(fluorosulfonyl)acetic acid reagent is employed as a difluorocarbene source for difluoromethylation of phenolic hydroxyl groups.
Application
2,2-Difluoro-2-(fluorosulfonyl)acetic acid may be used in the following processes:
- Preparation of 1-difluoromethyl-2-oxo-1,2-dihydropyridine analogs by reacting with the corresponding 2-chloropyridines.
- Prepration of silyl fluorosulfonyldifluoroacetate as new highly efficient difluorocarbene reagent for cyclopropanation of alkenes.
- Regio- and stereoselective free radical fluoroalkylation of terminal alkenes and alkynes with iododifluoromethanesulfonamides.

[reaction: see text] A novel one-pot synthesis of N-difluoromethyl-2-pyridones is described. N-(Pyridin-2-yl)acetamide derivatives were excellent precursors for the preparation of N-difluoromethyl-2-pyridone derivatives. Difluoromethylation of 2-acetaminopyridine derivatives was achieved with sodium chlorodifluoroacetate as a difluorocarbene source in the presence of a
