Iminocarbocation intermediates were in situ-generated by treating various oximes with trifluoromethanesulfonic anhydride (Tf2O) in the presence of triethylamine in toluene and nucleophilic trapping with amines or sodium enolates under mild conditions afforded the corresponding amidines and enamines. Some of the thus-obtained enamines were converted to 2-substituted 4-oxo-3-quinolinecarboxylic acid derivatives by subsequent intramolecular Friedel-Crafts acylation.

Enaminones, obtained by reaction of a primary amine with a β-diketone, can take three tautomeric forms: keto-enamine Ia, keto-imine Ib and imino-enol Ic.In general the keto-enamine form Ia is the most stable.Thi
