Oxidation of C-H compounds with peroxides catalyzed by polynuclear transition metal complexes in Si- or Ge-sesquioxane frameworks: A review

Polynuclear transition metal complexes in Si- or Ge-sesquioxane frameworks synthesized in recent years turned out to be efficient catalysts in oxidation of organic compounds with peroxides: H2O2, tert-butyl hydroperoxide (TBHP), meta-chloroperoxybenzoic acid (MCPBA). This brief review describes oxygenations by peroxides of alkanes to alkyl hydroperoxides, alcohols and ketones and benzene to phenol as well as oxidation of alcohols to the corresponding ketones. Some reactions with MCPBA occur stereoselectively. (C) 2017 Elsevier B.V. All rights reserved.
