Photocatalytic selective 1,4-oxyimination/diamination across C=C and N=N bonds to access structurally diverse N-N-N triazane derivatives

A highly selective and atom-economical multi-component remote difunctionalization strategy has been successfully developed. This strategy utilizes precise control over the radical properties of bifunctional precursors and the electronic traits of olefins and diazenes to achieve effective radical-mediated 1,4-oxyimination/diamination across C=C and N=N bonds. By capitalizing on compatibility and reactivity tuning, this approach enables the synthesis of complex triazine compounds with an N-N-N framework, providing a versatile tool for constructing diverse molecular structures. This metal-free method is atom-efficient and adaptable to various substrates, demonstrating remarkable tolerance for a broad range of functional groups.
