The authors synthesized a chiral multidentate ligand, (R,R,R,R)-N,N,N’,N’-tetra(2-hydroxy-2-phenylethyl)-1,3-xylylene diamine [(R)-I], which can support two metals at adjacent positions. Asym. transfer hydrogenation of acetophenone and its derivatives was conducted by using salt-free bimetallic lanthanoid complexes of (R)-I, and the combination of two samarium atoms and (R)-I was found to be the best catalyst system for asym. transfer hydrogenation of aryl ketones in high enantioselectivity (up to >99% ee). In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9Product Details of 120121-01-9).
(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Product Details of 120121-01-9
