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.
