Nitrolysis of syn,syn-2,4,6-tris-(n-propyl)-hexahydro-1,3,5-tripropionyl-s-triazine (3) with 1,1,1-trifluoroacetyl nitrate (TFAN) generated in situ from 1,1,1-trifluoroacetic anhydride and nitric acid in nitromethane gave mononitramine, dinitramine and trinitramine products depending on reaction duration and concentration of TFAN. Each of the three new nitramine products was purified and characterized by multi-nuclear magnetic resonance spectroscopy. An X-ray structure for syn,syn-2,4,6-tris-(n-propyl)-hexahydro-1,3,5-trinitro-s-triazine (syn,syn–10) is reported. The isomer syn,anti–3 did not yield analogous nitramine products by these nitrolysis conditions.

An operationally simple, efficient, and environmentally benign synthesis of 1,3,5-triacylperhydro-1,3,5-triazines in good yields by reaction of different organic nitriles and trioxane in the presence of phenylsulfonic acid functionalized mesoporous silica under mild conditions was examined. The yields of the corresponding 1,3,5-trisubstituted perhydro-s-triazines synthesized from acetonitrile, propionitrile, butyronitrile, benzonitrile, and 1.3.5-trioxane were 95.7%, 96.1%, 84.2%, and 98.1%, respectively. The products were characterized by 1H NMR, infrared, mass spectrometry, and elemental analysis. The mechanism of the formation of 1,3,5-triacylperhydro-1,3,5-triazines in acidic conditions was also described using a model reaction of butyronitrile with trioxane.

The 1,3,5-tripropanoylperhydro-s-triazine has been synthesized and its molecular formula established by means of 1H and 13C NMR, IR and mass spectroscopy.The X-ray structure of this compound is hexagonal, P63, Mr=255.3, a=12.083(5), c=5.362(2) Angstroem, V=678.0(4) Anstroem3, Z=2, Dx=1.25 g.cm-3, λ(CuKα)=1.54178 Angstroem, μ=7.525 cm-1, T=291 K, R=0.042 for 478 observed reflections with I>2.5 ?(I).The structure consists of isolated molecules, where the heterocycle is characterized by a distorted chair conformation.The three substituents C2H5CO occupy positions on the same side of the cycle and are oriented in a way to assume conjugation between the nitrogen free electron pair and the shell of the carbonyl group.

1,3,5-Triacylperhydro-1,3,5-triazines can be obtained in high yields by reaction of 1,3,5-trioxan with nitriles in solvents such as chlorobenzene using as catalyst an ion-exchange resin such as Amberlyst 15 with precise control of the hydration rate of the resin.

, (2008/06/13)
Hexahydro-1,3,5-trialkanoyl-s-triazines are produced by reacting a polymeric formaldehyde and an alkanoic acid amide in the presence of sulfuric acid catalyst and a liquid organic solvent or diluent while removing the water formed in the reaction by distillation, the amount of sulfuric acid catalyst employed being at least 0.05 mol per mol of said amide.
