Baral, Ek Raj;Lee, Jun Hee;Kim, Jeung Gon published 《Diphenyl Carbonate: A Highly Reactive and Green Carbonyl Source for the Synthesis of Cyclic Carbonates》. The research results were published in《Journal of Organic Chemistry》 in 2018.Application In Synthesis of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article conveys some information:
A practical, safe, and highly efficient carbonylation system involving a di-Ph carbonate, an organocatalyst, and various diols is presented herein and produces highly valuable cyclic carbonates. In reactions with a wide range of diols, di-Ph carbonate was activated by bicyclic guanidine 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as a catalyst, which successfully replaced highly toxic and unstable phosgene or its derivatives while maintaining the desired high reactivity. Moreover, this new system can be used to synthesize sterically demanding cyclic carbonates such as tetrasubstituted pinacol carbonates, which are not accessible via other conventional methods. 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 Application In Synthesis 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.
