An efficient synthesis of perhydro[1,2,4]triazolo[1,2-a][1,2,4]triazole-1,5-dithiones catalyzed by TiO2-functionalized nano-Fe3O4 encapsulated-silica particles as a reusable magnetic nanocatalyst

Immobilization of a nano-TiO2 catalyst on the surface of a magnetic SiO2 support was performed through the reaction of a Fe3O4@SiO2 composite with Ti(OC4H9)4via a simple process. The Fe3O4@SiO2-TiO2 nanocomposite was characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR), and a vibrating sample magnetometer (VSM). The Fe3O4@SiO2-TiO2 nanocomposite has been found to be an efficient catalyst for the synthesis of perhydro[1,2,4]triazolo[1,2-a][1,2,4]triazole-1,5-dithiones from the condensation of various aldazines and potassium thiocyanate in acetonitrile solvent at room temperature. It has been found that the nanocatalyst was recycled for up to 6 cycles with minimal loss in catalytic activity. The purpose of this research was to provide an easy method for the synthesis of perhydrotriazolotriazole derivatives by a robust and magnetically recoverable catalyst.

New synthesis of perhydrotriazolotriazoles catalyzed by TiCl 4under ambient conditions

Aromatic 2,3-diazabuta-1,3-dienes in glacial acetic acid with isothiocyanate in the presence of catalyst TiCl4 at room temperature produced via criss-cross cycloaddition reactions the corresponding perhydro[1,2,4]triazolo[1,2-a][1,2,4] triazole

Synthesis of 1,5-substituted-s-triazolinodino[1,2-a]-s-triazolidine-3,7-dithione and 1,2,4-triazolidine-3-thione derivatives from azines

Azines 1a-h react with ammonium thiocyanate in the presence of acetic acid to give 1,5-substituted-s-triazolinodino [1,2-a]-s-triazolidine-3,7-dithione 2a-e and 1,2,4-triazolidine-3-thione 2f-i derivatives as products.
