摘要：

Tetraethylammonium salt of a new Keggin-type 12-molybdovanadate nanocluster, [(C2H5)(4)N](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 was also shown to display excellent recyclability - it can be reused more than 10 times. (C) 2017 Elsevier B.V. All rights reserved.
