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.
