A mild and effective method is described for 11C-labeling of peptides selectively at the N-terminal nitrogen or at internal lysine positions. The presented method relies on the use of specific biphosphine palladium–methyl complexes and their high reactivity towards amino-carbonylation of amine groups in the presence [11C]carbon monoxide. The protocol facilitates the production of native N-11C-acetylated peptides, without any structural modifications and has been applied to a selection of bioactive peptides.
