Aryl diazonium ions are important in synthesis and chemical biology, and the acid-labile triazabutadiene can protect this handle for future use. We report a Suzuki coupling strategy that is compatible with the triazabutadiene scaffold, expanding the scope of synthetically available triazabutadienes. Shown herein, the triazabutadiene scaffold remains intact and reactive after coupling, as demonstrated by releasing the aryl diazonium ion to label a tyrosine-rich model protein.
