Substitution effect on the cylization/fluorination reaction of N-dienes in superacid.
The novel cyclization/fluorination reaction of N-dienes in superacid was extended to substituted substrates. The influence of the substitution on superelectrophilic character of dicationic intermediates was shown and its dramatic effect on the synthesis of fluoropiperidines was studied. On the basis of new dicationic alpha-chloronium ammonium intermediates, starting from halogen-substituted dienes, high-valued fluorinated piperidines were synthesized.

Cyclisation/fluorination of nitrogen containing dienes in superacid HF-SbF5: a new route to 3- and 4-fluoropiperidines.
Various N,N-diallylic amines and amides were rapidly converted to fluorinated piperidines after a novel cyclisation/fluorination reaction in superacid HF-SbF5.
