- Triacylperhydro-1,3,5-triazines over phenylsulfonic acid functionalized mesoporous silica
-
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.

- Synthesis of 1,3,5-Triacylperhydro-1,3,5-triazines Catalyzed by Ion-Exchange Resins
-
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.

- Reactions of Trimethylsilylmethyl Azide with Aromatic Acid Derivatives Catalyzed by Fluoride Ion
-
The treatment of an aromatic acid halide with trimethylsilylmethyl azide (TMSMA) in the presence of potassium fluoride and crown ether gave triazine, methanediamine, and benzamide derivatives, while the reaction of acid anhydride with TMSMA gave tertiary amine together with methanediamine and benzamide under similar conditions.
