Platinum catalyzed hydrogen‐deuterium exchange labeling of phenylalanine and tyrosine containing peptides in deuterium oxide is exemplified by the preparation of deuterium labeled leucine enkephalin and related peptides. NMR and mass spectral evidence indicates that the side chains of the aromatic residues...
