Synthesis of 1,2,4‐Triazine Compounds via Two Distinct One‐Pot Domino Protocols

1,2,4‐Triazine compounds were synthesized via two coupled domino strategies employing simple and readily available arylacetaldehydes/arylethyl alcohols as starting materials. The reactions proceed smoothly in one pot with the advantages of high functional groups tolerance, being transition metal‐free, and employing environmentally friendly oxidants such as I₂ and IBX , providing access to the desired 1,2,4‐triazine products in excellent yields.
