Vicinal diamines are a common structural motif in bioactive natural products, therapeutic agents, and molecular catalysts, motivating the continuing development of efficient, selective, and sustainable technologies for their preparation. We report an operationally simple and environmentally friendly protocol that converts alkenes and sodium azideboth readily available feedstocks-to 1,2-diazides. Powered by electricity and catalyzed by Earth-abundant manganese, this transformation proceeds under

Using standard protocols, the resultant 1,2-diazides can be smoothly reduced to vicinal diamines in a single step, with high chemoselectivity. Mechanistic studies are consistent with metalmediated azidyl radical transfer as the predominant pathway, enabling dual carbonnitrogen bond formation.
