An improved high yielding immobilization of vanadium Schiff base complexes on mesoporous silica via azide-alkyne cycloaddition for the oxidation of sulfides

Azide-alkyne [3+2] cycloaddition click reaction was found to be a simple yet improved approach for the efficient immobilization of oxo-vanadium(IV) tridentate Schiff base complexes to mesoporous silica via covalent attachment as it occurred under mild reaction conditions and provided high catalyst loading compared to the direct immobilization of oxo-vanadium( IV) tridentate Schiff base complex to 3-chloropropylsilyl functionalized silica support.
