Kiselyov, Alexander S. published the artcileA highly regioselective reaction of N-fluoropyridinium salts with stabilized sulfur, oxygen, and nitrogen nucleophiles: a convenient route to 2-substituted pyridines, HPLC of Formula: 107263-95-6, the publication is Journal of Heterocyclic Chemistry (1993), 30(5), 1361-4, database is CAplus.
2-Substituted pyridines I (R = phenoxy, phenylthio, imidazolyl, triazolyl, etc.) are efficiently obtained by the reactions of N-fluoropyridinium salts II (X = tetrafluoroborate, 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. The Reissert-Henze reaction of N-methoxypyridinium perchlorate to give I was unsuccessful.
