Abstract :
A vanadium Schiff base complex on nano silica was prepared by reaction of nano silica NH2-functionalized, 2,4-dihydroxy benzaldehyde and VO(acac)2. The VSBC@NS was used as an efficient and reusable heterogeneous catalyst for the selective oxidation of sulfides to sulfoxides and alcohols to aldehydes with H2O2 as an oxidant in methanol.
