  3. Abstract:
  4. Tetraethylammonium salt of a new keggin-type 12-molybdovanadate nanocluster, [(C2H5)4N]4[VMo12O40] (1) was synthesized via reaction between sodium tungstate, ammonium vanadate and tetraethylammonium bromide in acidic medium. Compound 1 was characterized by X-ray crystallography, FT-IR, UV–Vis and cyclic voltammetry and then applied as an efficient heterogeneous catalyst to oxidation of various organosulfides to sulfoxides with H2O2 at room temperature with 81–100% conversion and 60–99% selectivity. Nanocluster 1 was also shown to display excellent recyclability – it can be reused more than 10 times. © 2017 Elsevier B.V
