Patent

CA 2030809

The subject matter of the invention is a process for synthesis of sulfonylimidides of general formula M[(RSO2)2N]y, in which M represents a metal chosen from among the alkaline metals, the alkaline-earth metals, the rare-earths, Al, Sc, Y and Th, R represents a monovalent radical chosen from among the aliphatic radicals, having 1 to 8 carbon atoms, linear or branched, the alicyclic radicals having 3 to 8 carbon atoms, the arylic radicals having 3 to 8 carbon atoms, and y being a number equal to the valency ofM; and characterised by the fact that an ionic nitride of formula M3Ny in which M and y have the significance given above, is made to react with a sulfonyl halide corresponding to the formula RSO2X in which R has the significance given above, and X is chosen from F or Cl, in a polar aprotic solvent.

2030809 9011999 PCTABS00102 L'invention a pour objet un procédé de synthèse de sulfonylimidures. Le procédé de synthèse de sulfonylimidures de formule générale M[(RSO2)2N]y dans laquelle M représente un métal choisi parmi les métaux alcalins, les métaux alcalino-terreux, les terres rares, Al, Sc, Y et Th, R représente un radical monovalent choisi parmi les radicaux aliphatiques, ayant de 1 à 8 atomes de carbone, linéaires ou ramifiés, les radicaux alicycliques ayant de 3 à 8 atomes de carbone, les radicaux aryliques ayant de 3 à 8 atomes de carbone et y est un nombre égal à la valence de M, est caractérisé en ce que l'on fait réagir un nitrure ionique de formule M3Ny dans laquelle M et y ont la signification donnée ci-dessus, avec un halogénure de sulfonyle répondant à la formule RSO2X dans laquelle R a la signification donnée ci-dessus, et X est choisi parmi F ou Cl, dans un solvant aprotique polaire.
