Enantio‐ and regioselective: The intramolecular enantioselective aminofluorination of unactivated olefins was achieved by using a chiral iodo(III) difluoride salt. A highly regioselective aminofluorination of styrenes to access 2‐fluoro‐2‐phenylethanamines was also developed.

A novel palladium-catalyzedintramolecular oxidative aminofluorination of unactivatedalkenes has been developed, in which AgF was used as a key fluorinating reagent and PhI(OPiv)(2) as oxidant. The reaction afforded vicinal fluoroamine products with very high regioselectivity. A Pd(II/IV) catalytic cycle was proposed, and preliminary mechanistic studies indicated that direct reductive elimination

Application of a fluoroiodine analogue of the Togni reagent was studied in fluorocyclization reactions. In the presence of a transition‐metal catalyst the applied fluoroiodinereagent can be used for aminofluorination, oxyfluorination, and carbofluorination reactions. The described procedure has a very broad synthetic scope for preparation of functionalized hetero‐ and isocyclic compounds having a
