(S) -1-(2-Bromophenyl) ethanol (CAS#114446-55-8)

(S) -(-) -2-bromo-1-α-methylbenzyl mowa ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:

Ubwino:
(S)-(-) -2-bromo-1-α-methylbenzyl mowa ndi madzi opanda mtundu kapena opepuka achikasu okhala ndi fungo lapadera kutentha kutentha. Ili ndi mawonekedwe opunduka amitundu itatu monga momwe amapangira chiral mwachitsanzo, pali malo ozungulira omwe ali pamzere wa ma symmetry.

Ntchito: Itha kugwiritsidwanso ntchito ngati ligand pazothandizira stereoselective.

Njira:
Njira yokonzekera (S) - (-) -2-bromo-1-α-methylbenzyl mowa imatha kupezeka pochita ma aldehydes kapena ma ketones okhala ndi thionyl bromide pansi pamikhalidwe yamchere. Pambuyo zomwe zimachitika, kudzipatula kwa mankhwala achiral ndi kuyeretsedwa kwa chiral kwa mankhwala a chiral kumafunika.

Zambiri Zachitetezo:
Kukhudzana ndi khungu ndi maso kuyenera kupewedwa.
Panthawi yogwira ntchito, mpweya wabwino uyenera kutetezedwa kuti usapumedwe kapena kumeza.
Chigawochi chikhoza kuwola pa kutentha kwambiri kuti chitulutse mpweya woipa, womwe umayenera kusungidwa kutali ndi magwero oyatsira ndi kutentha kwakukulu.
Zida zodzitetezera zoyenerera monga magolovesi a labu ndi magalasi otetezera chitetezo ziyenera kuvalidwa mukamagwiritsa ntchito.
Miyezo ndi njira zotetezera zoyenera ziyenera kutsatiridwa posamalira ndi kutaya.
Muzochita zenizeni, zochitika zenizeni komanso zoyesera ziyeneranso kuganiziridwa.
