摘要: Abstract Chemo selectivity of some N -aryl formamides with pentafluoropyridine under basic conditions in dry THF was investigated. The aromatic nucleophilic substitution enol–imines derived from occurs at the 4-position pyridine ring by both oxygen and nitrogen site depending on nature substituent; electron releasing group, attack accomplished atom an withdrawing reaction formamide anions proceeded via site.
