We report the facile preparation of palladacycles as storable arylpalladium(II) reagents from acetanilides via cyclopalladation. The palladacycles exhibit good stability in PBS buffer and are capable of functionalizing a metabolically encoded HPG-containing protein, thus providing a new type of biocompatible organometallic reagent for selectively functionalizing the alkyne-encoded proteins.
