CAS: {{114446-55-8 (s) {1}} (2- bromophenyl) ethanol

Khoom:
(S) -1- ({2- Bromophenyl) ethanol yog kua xim tsis muaj xim lossis kua txob rau ntawm chav sov. Nws muaj deformable steo keeb kwm vim tias nws yog chairal compound, piv txwv li, muaj lub chaw chiral ntawm cov molecular symmetry axis.

Nqe lus piav qhia:

{{0 {0}} bromo-alpha-Methylbenyleny-Methylbenchyl cawv yog Chairal Molecule nrog ob daim iav-cov khoom siv. Cov (s) - (+) - enantiomer yog nquag, thaum lub (r) - (-) - enantiomer tsis yog. 2- bromo-alpha-menylbenencoyl cawv tuaj yeem hloov pauv los ua ntawv {13}} lub ntsej muag bromo-altylbendehyde, uas yog ib qho kev sib txuas ntawm allylic nrog kev sib raug zoo rau nws. Ob qho enantiomers muaj cov tshuaj sib txawv vim tias lawv muaj feem cuam tshuam nrog txoj hauv kev uas tsis tso cai rau kev sib hloov. Cov (s) - (+) - enantiomer ntawm {19}} bromo-alcha-menylbenus binds rau phosphorus ligands, thaum lub (r) - (-) - enantiomer tsis.

Siv:

Nws kuj tseem tuaj yeem siv los ua ligand rau kev ua yeeb yam catalystive.

Txoj kev npaj:
(S) -1- ({2- bromophenyl) ethanol tuaj yeem npaj tau los ntawm etharots aldehydes bromide nyob rau hauv Alkaline tej yam kev mob. Tom qab cov tshuaj tiv thaiv tshwm sim, kev sib cais ntawm cov teb tsis yog-chiral thiab cov chiral ua kom huv ntawm cov chairal tebchaw yuav tsum tau ua.
