(TEMPO+)-mediated three-component diverse transformation of vinyl azides under metal-free conditions is described. The reaction protocols are operationally simple and conducted at ambient temperature, allowing to access various TEMPO-trapped ketones, amides, and α-alkoxyalkyl azides. Preliminary mechanistic studies indicate that an alkene radical cation-mediated radical–radical cross-coupling C–O bond
