Abstract
(EN) Methods of producing N,N-dimethyl sulfamoyl fluoride and related derivatives of the formula F—S(O)2—NR2 (I) by contacting a sulfamoyl nonfluorohalide compound of the formula X—S(O)2—NR2 (II) with anhydrous hydrogen fluoride under conditions sufficient to produce the N,N-dimethyl sulfamoyl fluoride or derivative thereof of Formula I, wherein R in each of Formulas I and II is, independently, a linear or branched alkyl, alkenyl, or alkynyl group containing 1 to 12 carbon atoms, the Rs can be joined to form a cyclic amine with the N, and X is any one of chlorine, bromine, and iodine.
(FR) L'invention concerne des procédés de production de fluorure de N,N-diméthyl sulfamoyle et de dérivés apparentés de formule F-S(O)2-NR2 (I) par mise en contact d'un composé d'halogénure non fluoré de sulfamoyle de formule X-S(O)2-NR2 (II) avec du fluorure d'hydrogène anhydre dans des conditions suffisantes pour produire le fluorure de N,N-diméthyl sulfamoyle ou un dérivé de celui-ci de formule I, R dans chacune des formules I et II étant, indépendamment, un groupe alkyle, alcényle ou alcynyle linéaire ou ramifié contenant 1 à 12 atomes de carbone, les R pouvant être joints pour former une amine cyclique avec N, et X étant l'un quelconque parmi le chlore, le brome et l'iode.
