Bihanic, Camille;Stanovych, Andrii;Pelissier, Franck;Grison, Claude published 《Putting Waste to Work: The Demonstrative Example of Pyrite Quarry Effluents Turned into Green Oxidative Catalysts》. The research results were published in《ACS Sustainable Chemistry & Engineering》 in 2019.Quality Control of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article conveys some information:
In the context of exponentially growing problems of pollution and waste, the design of ecofriendly processes for turning the current treatment of effluents into sustainable catalysts represents a great opportunity. Wastewater arising from pyrite quarrying is selected as a model example. The acidity of pyrite effluents leads to solubilization of useful cations: MnII and FeII/FeIII. Their chem. properties are an opportunity to promote innovative studies of oxidation in organic synthesis. The controlled addition of NaOH and a co-oxidant (H2O2) onto the effluents allows generation of new, oxidative catalysts. MP-AES anal., XPS, XRPD, BET, TEM, HRTEM, and EDX studies were performed to characterize the new and efficient catalysts. Oxidation of alcs. into carbonyl compounds, oxidative cleavage of 1,2-diols, and epoxidation of alkenes are described. The experimental procedure involved many compounds, such as rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
Desymmetrization of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas:579-43-1 Quality Control of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol) using chiral phosphine catalyst has been reported. Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
