Epoxidation of Alkenes and Oxidation of Alcohols with Hydrogen Peroxide Catalyzed by a Fe (Br8TPPS) Supported on Amberlite IRA-400
Iron (III) meso-tetrakis(p-sulfonatophenyl)-β-octabromoporphyrin supported on Amberlite IRA- 400 [Fe(Br8 TPPS)-Ad-400] is a robust and efficient catalyst for oxidation of alkenes and alcohols at room temperature. The catalyst exhibits a high activity and stability in hydrocarbon oxidation by H2 O2 . The method was useful in the oxidation of various primary, secondary-aliphatic, alicyclic and ar...
متن کاملUrea-hydrogen peroxide/silica phosphoric acid-catalyzed oxidation- condensation Tandem reaction: One-pot synthesis of 2-substituted benzimidazoles from alcohols
An efficient one-pot oxidation/condensation tandem process has been developed for the synthesis of 2-substituted benzimidazole derivatives from benzylic alcohols and 1,2-phenylenediamine with use of urea-hydrogen peroxide/silica phosphoric acid as a bifunctional catalyst. This method provides a rapid and efficient access to 2-substituted benzimidazoles.

متن کاملEpoxidation of alkenes and oxidation of alcohols with hydrogen peroxide catalyzed by a manganese(V) nitrido complex.
The manganese(V) nitrido complex (PPh(4))(2)[Mn(N)(CN)(4)] is an active catalyst for alkene epoxidation and alcohol oxidation using H(2)O(2) as an oxidant. The catalytic oxidation is greatly enhanced by the addition of just one equivalent of acetic acid. The oxidation of ethene by this system has been studied computationally by the DFT method.
متن کاملOptimization of Soil Aquifer Treatment by Chemical Oxidation with Hydrogen Peroxide Addition
Trace organic compounds (TrOCs), mostly found in secondary effluents, have a potential impact on the environment, affecting surface water, groundwater, and especially aquatic ecosystems. The present study focuses on oxidation of five selected TrOCs in column experiments, by simulating Soil Aquifer Treatment (SAT) integrated with Fenton-like reaction, using Granular Ferric Hydroxide (GFH) as a c...
