  • Process for the manufacture of 1-substituted-4-fluoro-1,4-diazoniabicyclo[2.] octane salts
    Patent number: 5631372
    Abstract: A process for producing 1-substituted-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane salts having the formula ##STR1## wherein the Z substituent is OH, OR, OC(O)R, SO.sub.3, SO.sub.2 R, NO.sub.2, NO, or PO(OR).sub.2, wherein R is an aryl or C.sub.1 -C.sub.8 alkyl group; n is 0, 1 or 2; each of R.sub.1, R.sub.2, R.sub.3, P.sub.4 and R.sub.5 independently represent hydrogen, C.sub.1 to C.sub.8 alkyl, or aryl 1-substituted-1,4-diazoniabicyclo[2.2.2]octane or 1,4-diazoniabicyclo[2.2.2]octane mono-N-oxide is reacted to attach the Z group and then the result is reacted with molecular fluorine in the presence of a solvent that substantially does not react with fluorine and a fluoride scavenger that results in an X counter ion. These compounds are useful as fluorinating agents for the introduction of fluorine into organic compounds.
