What is Sodium 1,1-difluoroethylsulfinate?
The Uses of Sodium 1,1-difluoroethylsulfinate
DFES-Na provides a direct approach to fluorinated heteroarylether bioisosteres by appending a 1,1-difluoroethyl group operationally simple and robust protocol. This reagent was developed by the Baran Group and is one of several reagents for the direct alkylation of heterocycles.
