Abstract

The invention relates to a process of generating N(CF3)2 anions by reacting a metal fluoride of formula MFx with a compound of formula RFSO2N(CF3)2, (CF3)2N(SO2CF2)mSO2N(CF3)2 or RFCON(CF3)2. The invention further relates to the use of the N(CF3)2 anions as a reagent for the introduction of halogen or other organic groups into organic molecules.
