New perspective to Keplerate polyoxomolybdates: Green oxidation of sulfides with hydrogen peroxide in water

Highly Selective Oxidation of Sulfides to Sulfones by H2O2 Catalyzed by Porous Capsules

“…In previous works, it was reported that the selective oxidation of various sulfides with H 2 O 2 was catalyzed by a Keplerate polyoxometalates Mo 72 M 30 (M = V, Cr, Fe). However, in this work Mo 72 Fe 30 indicated low catalytic performance compared to other catalysts [25]. Interestingly, Mizuno discovered that the strong Lewis acidity of W atoms in polyoxometalate plays an important role in the oxidation [26].…”

Selective Oxidation of Sulfides to Sulfones by H2O2 Catalyzed by Fe-Substituted Sandwich Type Polyoxometalate

“…During our continuous study into the selective oxidation of organic compounds [43][44][45][46][47][48][49][50][51]. We recently found that tetra(tetrabuthylammonium) salt of polyoxometalates are efficient catalysts for selective oxidation of sulfides.…”

A nanoscopic icosahedral {Mo72Fe30} cluster catalyzes the aerobic synthesis of benzimidazoles

“…17 Aer that, other research groups including us, tried to use different Keplerates in a variety of organic transformations. [18][19][20][21][22][23][24][25] As {Mo 72 Fe 30 } as concerned, suldes oxidation, 17,23 and epoxidation of olens, 22 are few works performed in the present of crystalline form of cluster, and to the best of our knowledge, there is no report on catalytic utilization of amorphous {Mo 72 Fe 30 } as a high yield and easymade heterogeneous catalyst in organic transformation yet. Following our ongoing research on catalytic activity of Scheme 1 Synthesis of benzimidazole derivatives by {Mo 72 Fe 30 } nanoclusters and O 2 as oxidant.…”
