A metal-free iodine/TBHP-mediated oxidative C–N bond formation for the one-pot synthesis of N-fused 1,2,4-triazoles and related heterocycles via cyclization has been developed. This reaction which is amenable to scale-up affords the corresponding products with good to excellent yields and tolerates a wide range of functional groups.
