Synthesis and application of bulky phosphoramidites: highly effective monophosphorus ligands for asymmetric hydrosilylation of styrenes was written by Zhang, Feng;Fan, Qing-Hua. And the article was included in Organic & Biomolecular Chemistry in 2009.Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol This article mentions the following:
A series of bulky monodentate phosphoramidite ligands were synthesized from chiral 3,3′-diaryl substituted BINOL derivatives and achiral or dendritic amines in good yields. Asym. hydrosilylation of styrenes with trichlorosilane in the presence of palladium complexes of these bulky ligands gave chiral silanes in high yields with excellent activity and productivity. Oxidation of these chiral silanes with hydrogen peroxide gave the corresponding chiral secondary alcs. in up to 96% ee. In the experiment, the researchers used many compounds, for example, (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol).
(S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol
