Abstract
F-alkyl chains perturb the reactivity of substrates in an often unpred ictable way. F-alkyl azirine and aziridine carboxylates were prepared from F-alkynylesters, in 80 and 60% yield, respectively, and were foun d to display reactivities different from those of their hydrocarbon an alogs. Thus, F-alkylazirines (5) give addition products easily but res ist ring opening, while the F-alkylaziridines (8) are extremely stable , both towards nucleophilic and electrophilic reagents and irrespectiv e of the medium used, neutral, acid or basic.
