Manganese-Catalyzed Asymmetric Hydrosilylation of Aryl Ketones was written by Ma, Xiaochen;Zuo, Ziqing;Liu, Guixia;Huang, Zheng. And the article was included in ACS Omega in 2017.SDS of cas: 120121-01-9 This article mentions the following:
Nonracemic (oxazolinyl)pyridinylimine manganese complexes I (R = i-Pr, Ph2CH; R1 = H, Me; R2 = PhCH2, i-Pr, t-Bu) were prepared as catalysts for the enantioselective hydrosilylation of aralkyl ketones. In the presence of I (R = Ph2CH; R1 = Me; R2 = t-Bu), aralkyl ketones such as 4-R3C6H4COMe (R3 = Cl, i-Bu, t-Bu, cyclohexyl, n-Pr, MeO, Br, I, H) with Ph3SiH and NaBHEt3 in toluene to yield nonracemic benzylic alcs. such as (R)-4-R3C6H4CH(OH)Me (R3 = Cl, i-Bu, t-Bu, cyclohexyl, n-Pr, MeO, Br, I, H) in 48-99% yields and 66:34-96.5:3.5 er. The structure of I路2 CH2Cl2 (R = Ph2CH; R1 = Me; R2 = t-Bu) was determined by X-ray crystallog. In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9SDS of cas: 120121-01-9).
(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.SDS of cas: 120121-01-9
