Syntheses with s‐Triazine

The preparation and properties of s‐triazine are discussed. Nucleophilic reagents (even water) readily attack s‐triazine. Thus, open‐chain and heterocyclic compounds, e.g. formamidines, aminomethylene compounds, and triazole, pyridine, and pyrimidine deravatives are accessible from s‐triazine. With amidines and imido ethers substituted triazines are obtained (by trans‐triazination).The latter are formed via open‐chain intermediates.
