2-Substituted pyridines are efficiently obtained by the reactions of N- fluoropyridinium tetrafluoroborate or triflate with anions derived from benzenethiols, phenols, azoles, cyanamide, and with azide anion. The results are consistent with a nucleophile addition at the position 2 of the N- fluoropyridinium cation as the major reaction pathway.
