1,3,5-Triazine, also called '''s-triazine', is an organic chemical compound with the formula (HCN). It is a six-membered heterocyclic aromatic ring, one of several isomeric triazines. s-Triazine —the "symmetric" isomer—and its derivatives are useful in a variety of applications.
==Preparation== Symmetrical 1,3,5-triazines are prepared by trimerization of certain nitriles such as cyanogen chloride or cyanamide. Benzoguanamine (with one phenyl and 2 amino substituents) is synthesised from benzonitrile and dicyandiamide. In the Pinner triazine synthesis (named after Adolf Pinner) the reactants are an alkyl or aryl amidine and phosgene. Insertion of an N-H moiety into a hydrazide by a copper carbenoid, followed by treatment with ammonium chloride also gives the triazine core.
