Palladium ligand choice suppresses competing indane formation
This research indicates that palladium-catalyzed coupling of 2-(but-3-en-1-yl)phenyl triflates with amine nucleophiles can produce 2-amino tetralins and 1-aminomethyl indanes, and that the ligand t BuPhCPhos suppresses a competing intramolecular Heck arylation reaction.
