The present study describes the design and synthesis of novel nano N-bromo porphyrazin (N-bromo tetra-2,3-pyridiniumporphyrazinato oxo-vanadium tribromomethanide [VO(TPPABr)] CBr3) as an efficient, recyclable and thermal stable heterogeneous catalyst for chemo and homoselective oxidation of sulfides to sulfoxides and benzyl alcohols to benzaldehydes. This ecofriendly heterogeneous catalyst was fully characterized by FT-IR spectra, UV–Vis spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermal gravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDX) and elemental analysis (CHN). The synthesized catalyst exhibited a high-performance and considerable reusability.

Silica vanadic acid (vanadium has been supported on silica) is applied as an efficient, highly reusable and heterogeneous catalyst for the selective oxidation of sulfide to sulfoxide using hydrogen peroxide and in the acetonitrile as a solvent at room temperature. The catalyst can be easily recovered and reused for ten reaction cycles without considerable loss of activity. Also, some advantages of this method were applicable at large scales, high TON of catalyst, chemoselectivity, easy work-up and short reaction time.
