The present invention is directed to a process for preparing a N,N'-difluorodiazoniabicycloalkane salt of the formula: (see formula I) by reacting a corresponding diazabicycloalkane or diazabicyclo- alkane Br.slzero.nsted acid salt and fluorine in the presence of a Br.slzero.nsted acid or in the presence or absence of a base, by reacting a corres- ponding N,N'-difluorodiazoniabicycloalkane salt and an acid or salt, by reacting a corresponding diazabicycloalkane and fluorine in the presence of a Br.slzero.nsted acid and then reacting an intermediate product and an acid or salt, or by reacting a corresponding diaza- bicycloalkane Br.slzero.nsted acid salt and fluorine in the presence or absence of a base and then reacting an intermediate product and an acid or salt.
La présente invention concerne des procédés de production de sels de N,N'-difluorodiazoniabicyclo-alcanes représentés par la formule générale (I), en présence d'un acide de Bronsted, ou bien en présence ou en l'absence d'une base. Ces procédés consistent en la mise en réaction d'un diazabicycloalcane ou d'un sel d'acide de Bronsted d'un diazabicycloalcane avec du fluor; la mise en réaction d'un sel correspondant de N,N'-difluorodiazoniabicyclo-alcane avec un acide ou un sel; la mise en réaction d'un diazabicycloalcane correspondant, successivement avec du fluor et un acide ou un sel; ou la mise en réaction d'un sel d'acide de Bronsted d'un diazabicycloalcane correspondant, successivement avec du fluor et un acide ou un sel.
