triflates to afford cyclic sulfamide products is described. In contrast to other known Pd‐catalyzed alkenecarboaminationreactions, these transformations may be selectively induced to occur by way of either anti‐ or syn‐aminopalladation mechanistic pathways by modifying the catalyststructure and reactionconditions.

Abstract A facile Pd-catalyzed intramolecular aminofluorination reaction of allylic sulfamides was developed that can be used to prepare fluorinated 1,3-diamine derivatives. Acetic acid was essential for regulation to give the major 6-endo cyclization products.
