A facile development of chiral alkenylboranes (e.g., I) by the hydroboration of chiral diynes with Piers’ borane was successfully achieved for the first time. With the combination of the in situ generated chiral alkenylboranes and tri-tert-butylphosphine as frustrated Lewis pair catalysts, the metal-free asym. hydrogenation of silyl enol ethers was realized to furnish a wide range of optically active secondary alcs. in high yields and up to 99% ee. In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9Name: (R)-1-(3-Chlorophenyl)ethanol).
(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Name: (R)-1-(3-Chlorophenyl)ethanol
