synthesized by a palladium(0)‐catalyzed intramolecular chlorocarbamoylation reaction of alkynes. A relatively underexplored class of caged phosphine ligands is uniquely suited for this transformation, enabling high levels of reactivity and exquisite transselectivity. This report entails the first transition‐metal‐catalyzed atom‐economic addition of a carbamoyl chloride across an alkyne.
