Abstract
The invention relates to a process for the synthesis of sulfonylimides. The process for the synthesis of sulfonylimides of the general formula M[RSO.sub.2).sub.2 N].sub.y, in which M represents a metal chosen from alkali metals, alkaline earth metals, rare earths, Al, Sc, Y and Th, R represents a monovalent radical chosen from linear or branched aliphatic radicals having 1 to 8 carbon atoms, alicyclic radicals having 3 to 8 carbon atoms, aryl radicals having 3 to 8 carbon atoms, and y is a number equal to the valence of M, is characterized in that an ionic nitride of the formula M.sub.3 N.sub.y, in which M and y have the meaning given above, is reacted with a sulfonyl halide of the formula RSO.sub.2 X, in which R has the meaning given above, and X is chosen from F or Cl, in an aprotic polar solvent.
