Chemical labelling can significantly extend the structures and functions of proteins for advanced applications. Herein, a highly efficient bench-stable reagent diazo-azide was designed and synthesized for the incorporation of tetrafluorinated aromatic azides into proteins via the diazonium coupling. The diazo-azide-labelled proteins could be further functionalized via the nonhydrolysis Staudinger reaction
