, (2008/06/13)
Novel N-fluorotriazinium electrophilic fluorinating agents have the Formula I: wherein three A moieties are independently CR, where each R is, independently, hydrogen, halogen, hydroxyl, (primary, secondary or tertiary) amino, amino, cyano, perfluorothio, hydroxysulfonyl, halosulfonyl, hydrocarbyloxysulfonyl, or a carbon-containing substituent selected from the group consisting of optionally substituted hydrocarbyl, hydrocarbyloxy, hydrocarbyloxycarbonyl, and hydrocarbylthio groups, and at least one R is neither hydrogen nor halogen; two A moieties are independently Z, where each Z is independently nitrogen or a quaternary nitrogen atom and Y is a counterion or group of counterions which are inert to chemical attack by fluorine, or adjacent triazinium moieties are linked by a common R substituent to provide an oligomer or polymer. Preferably the compounds are 1,3,5-triazinium compound in which all R are the same, optionally perfluorinated, alkyl or alkoxy groups; Z1 and Z2 are both nitrogen and Y? is triflate. Compounds of Formula I are especially useful in fluorinating carbanionic species or activated aromatic compounds.

N-fluorotriazinium salts, especially those of the following Formula I, are electrophilic fluorinating agents useful in fluorinating, preferably in a nitromethane solvent, carbanionic species and/or activated aromatic compounds:wherein three A moieties are independently CR, where each R is, independently, hydrogen, halogen, (primary, secondary or tertiary) amino, hydroxyl, amino, cyano, perfluorothio hydroxysulphonyl, halosulphonyl, hydrocarbyloxysulphonyl,, or a carbon-containing substituent selected from optionally substituted hydrocarbyl, hydrocarbyloxy, hydrocarbyloxycarbonyl, and hydrocarbylthio groups; two A moieties are independently Z, where each Z is independently nitrogen or a quaternary nitrogen atom and Y is a counterion or group of counterions which are inert to chemical attack by fluorine, and oligomers or polymers thereof in which adjacent triazinium moieties are linked by a common R substituent. Preferably the cation of the salt is 2,4,6-trichloro-1,3,5-triazinium.
