Anwendungen & Verwendung

Verwenden

1,3,5-Triazine is a reagent in oxidation reactions, in synthesis of heterocycles. Triazine derivatives are used as herbicides, pharmaceuticals, complexation agents, peptidomimetic building blocks, and dyes.

Herstellung & Synthese

synthetische

Symmetrical 1,3,5-triazines are prepared by trimerization of certain nitriles such as cyanogen chloride or cyanimide. 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.Amine-substituted triazines called Guanamines are prepared by the condensation of cyanoguanidine with the corresponding nitrile:(H2N)2C=NCN + RCN → (CNH2)2(CR)N3
