Webb11 juli 2024 · The intramolecular aminofluorination of homoallylamine derivatives using a reagent system of PhI(OAc)2 and Py·HF in CH2Cl2 at room temperature for 5 h gave N-tosyl-3-fluoropyrrolidines in good to ... WebbSN2’path is observed with organocopper reagents, 4 whereas 30 oxygen-centered nucleophiles,5 halogens6 and sulfur-stabilized carbanions,3,7 lead preferentially to S N2 products. The latter examples suggest that the regioselectivity of the ring opening reactions of vinylaziridines is governed mainly by the type of nucleophile.
