Stable and solubilized active Au atom clusters for selective epoxidation of cis-cyclooctene with molecular oxygen
The ability of Au catalysts to effect the challenging task of utilizing molecular oxygen for the selective epoxidation of cyclooctene is fascinating. Although supported nanometre-size Au particles are poorly active, here we show that solubilized atomic Au clusters, present in ng ml-1 concentrations and stabilized by ligands derived from the oxidized hydrocarbon products, are active. They can be...
متن کاملOxygen carriers based on electrochemically reduced trinitroarenes.
1,3,5-Trinitrobenzene, 2,4,6-trinitrotoluene and 1-methoxy-2,4,6-trinitrobenzene undergoes reversible dimerization, after electrochemical reduction of two units of corresponding anion radical. The pi-dimer formed captures molecular oxygen (O(2)) leading to a sigma(o-o)(H)-adduct, in an atmosphere of oxygen or even air. The sigma(o-o)(H)-adduct is able to reversibly bind and remove dioxygen afte...
متن کاملInfluence of Nitrogen Bases on Epoxidation of Cyclooctene with Sodium Periodate Catalysed by Manganese(III) Porphyrins
Effects of imidazoles and substituted pyridines and pure s-donors on the oxidation of cyclooctene with NaIO4 by 5,10,15,20-tetraphenylporphyrinato-manganese(III) acetate, Mn(TPP)OAc, and 5,10,15,20-Tetramesitylporphyrinato-manganese(III) acetate, Mn(TMP)OAc, catalysts in CH2Cl2-H2O solvent are studied. Coordination of the nitrogen donors to the Mn...
متن کاملCatalytic Epoxidation of Limonene
The epoxidation of limonene with hidrogen peroxide was studied over zeolite Tibeta (a large pore material) and heteropoly acids on carbono and alumina supported. PW11/C was catalyst the best tested. Introduction In the last years, the increase in environmental restrictions lead to the search for new oxydant systems to replace the traditionals in order to avoid the generation of polluting efflue...
