5-triazines were smoothly formed via TBHP-mediated direct oxidative coupling of amidine and methylarenes. This tandem oxidation–imination–cyclization transformation exhibits a straightforward protocol to prepare 1,3,5-triazines from easily available starting materials and green oxidants undermetal-freeconditions.
