Selectivity adjustment of Fe3O4 MNPs based silver catalyst in oxidation of sulfides with classical and ultrasonic methods and synthesis of 5-substituted 1H-tetrazoles from aryl nitriles in water

The surface of the Fe3O4 has been functionalized with 3-chloropropyltrimethoxysilane, which undergoes an SN2 substitution reaction of the chloro group with the nitrogen of ligand (creatinine), offering the Fe3O4@Creatinine. A new recyclable Ag attached Fe3O4 MNPs (Fe3O4 @Creatinine@Ag) has been prod...
