Abstract

1-Alkyl-1,2,4-triazoles were quaternized at N-4 in >98% isolated yields using polyfluoroalkyl halides under neat reaction conditions at 100-120 °C to form 1-R-4-Rf-triazolium (Taz) halides. Metathesis of these polyfluoroalkylated triazolium halides with fluorine-containing anions led to the formation of new ionic liquids, [R(Rf)Taz]+Y-.

Key words

fluoroalkylation - metathesis - fluorine-containing ionic liquids - triazolium quaternary salts
