Safety of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol《Convenient synthesis of ethylene carbonates from carbon dioxide and 1,2-diols at atmospheric pressure of carbon dioxide》 was published in 2016. The authors were Kitamura, Tsugio;Inoue, Yusuke;Maeda, Taisei;Oyamada, Juzo, and the article was included in《Synthetic Communications》. The author mentioned the following in the article:
An efficient and convenient synthesis of ethylene carbonates was achieved by the reaction of carbon dioxide with 1,2-diols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), followed by treatment with 1-bromobutane. This DBU-promoted transformation proceeded at atm. pressure of carbon dioxide at 25°C and gave ethylene carbonates in good yields. 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 Safety 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.
