Cano, Rafael;Perez, Juana M.;Ramon, Diego J. published 《Osmium impregnated on magnetite as a heterogeneous catalyst for the syn-dihydroxylation of alkenes》. The research results were published in《Applied Catalysis, A: General》 in 2014.Recommanded Product: rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article conveys some information:
A new catalyst derived from osmium has been prepared, fully characterized and tested in the dihydroxylation of alkenes. The catalyst was prepared by wet impregnation methodol. of OsCl3·3H2O on a com. micro-magnetite surface. The catalyst allowed the reaction with one of the lowest osmium loadings for a heterogeneous catalyst and was selective for the monodihydroxylation of 1,5-dienes. Moreover, the catalyst was easily removed from the reaction medium by the simple use of a magnet. The selectivity of catalyst is very high with conversions up to 99%. Preliminary kinetics studies showed a first-order reaction rate with respect to the catalyst. To complete the study, the researchers used 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 Recommanded Product: 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.
