Hexahydro-1,3,5-triazine

They are reduced derivatives of 1,3,5-triazine, which have the formula (CHN)3, a family of aromatic heterocycles.

These triacyltriazines arise from the reaction of hexamethylene tetraamine with acid chlorides or the condensation of amides with formaldehyde.

[4] Unlike the parent triazines, the hexahydro derivatives are conformationally flexible.

They have the formula (RNC(O))3 and based on the isocyanuric (trione) tautomer of cyanuric acid.

Examples include Mo(CO)3[(CH2)3(NMe)3] formed from the TACH ligand and molybdenum hexacarbonyl.
