obtained using Na2S2O4/NaHCO3 promoted addition-cyclization of per(poly)fluoroalkyl iodides or perhaloalkanes with 1,6-heptadienes. The stereochemistry of hydrodehalogenation products (5, 6, 8, 9) was determined based on their 1H-NMR spectra. γ-Lactams and γ-lactones bearing fluoroalkyl groups were obtained using the same system promoted per(poly)fluoroalkylation reaction with N-allyl acrylamides (10) and
