Synthesis of 1,2-Diazides
CHAMPO, a new aminoxyl radical catalyst, enables an electrochemical diazidation of a broad range of alkenes in good yields. Mediated by an anodically generated charge-transfer complex in the form of CHAMPO-N3, radical diazidation was achieved without the need for a transition metal catalyst or a chemical oxidant.

A stable azidoiodine(III) reagent is used as an efficient azide radical source for efficient copper-catalyzed oxyazidation and diazidation of styrenes in good yields. Various synthetically useful functional groups are tolerated under the mild reaction conditions.
