Patent

CA 2361609

This invention relates to a process for the generation of N(CF3)2 anions characterised by the reaction of a metal fluoride of formula MFx with a compound of formula RFSO2N(CF3)2, (CF3)2N(SO2CF2)mSO2N(CF3)2 or RFCON(CF3)2. M, x, RF, and m have the values given in the specification. It also relates to the use of said anions for the introduction of N(CF3)2 groups into organic molecules.

Cette invention a trait à un nouveau procédé de production d'anions-N(CF¿3?)¿2? se caractérisant par la mise en réaction d'un fluorure métallique correspondant à la formule MF¿x? avec un composé correspondant à la formule R¿F?SO¿2?N(CF¿3?)¿2?N(SO¿2?CF¿2?)¿m? ou à la formule R¿F?CON(CF¿3?)¿2?. M, x, R¿F? et m ont les valeurs indiquées dans le descriptif. L'invention concerne également l'emploi qui est fait de ces anions pour introduire des groupes N(CF¿3?)¿2? dans des molécules organiques.
