Applications of Ruthenium Hydride Borohydride Complexes Containing Phosphinite and Diamine Ligands to Asymmetric Catalytic Reactions was written by Guo, Rongwei;Chen, Xuanhua;Elpelt, Christian;Song, Datong;Morris, Robert H.. And the article was included in Organic Letters in 2005.COA of Formula: C8H9ClO This article mentions the following:
A series of novel trans-ruthenium hydride borohydride complexes with chiral phosphinite and diamine ligands were synthesized. They can be used in the asym. transfer hydrogenation of aryl ketones, including base-sensitive ones, to give chiral alcs. in moderate to good enantioselectivities (up to 94% ee). They are also efficient catalysts for the Michael addition of malonates to enones with enantioselectivities of up to 90%. This kind of catalyst allows a one-pot tandem Michael addition/H2 hydrogenation protocol to build structures with multiple chiral centers. In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9COA of Formula: C8H9ClO).
(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.COA of Formula: C8H9ClO
