The present invention relates to the preparation and uses of 1-substitued-4- fluoro-1,4-diazoniabicyclo[2.2.2]octane salts, specifically 1-hydroxyl-4- fluoro-1,4-diazoniabicyclo[2.2.2]octane salts as reagents for the introduction of fluorine in organic compounds. In formula (I) Z is OH, OR, OC(O)R, SO3, SO3, SO2R, NO2, NO, or P(O) (OR)2 with R being an aryl or C1-C8 alkyl, where n represents 0, 1 or 2; each R1, R2, R3, R4 and R5 independently represents hydrogen, C1-C8 alkyl, aryl, C1-C8 alkyl; and each X- independently represents a counterion or 2X- represents a single divalent counterion.
L'invention concerne la préparation et les utilisations de sels de 4-fluoro-1,4-diazoniabicyclo[2.2.2]octane à substitution en position 1, spécifiquement de sels de 1-hydroxyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane comme réactifs destinés à l'introduction de fluore dans des composés organiques. Dans la formule (I) desdits sels, Z représente OH, OR, OC(O)R, SO¿3?, SO¿3?, SO¿2?R, NO¿2?, NO, ou P(O) (OR)¿2?, R représentant un aryle ou un alkyle C¿1?-C¿8?, où n représente 0, 1 ou 2; chaque R¿1?, R¿2?, R¿3? R¿4? et R¿5? représente indépendamment hydrogène, alkyle C¿1?-C¿8?, aryle, alkyle C¿1?-C¿8? et chaque X?-¿ représente indépendamment un contre ion ou 2X?-¿ représente un contre ion individuel divalent.
