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

(S)-(-)-2-bromo-1-α-methylbenzyl utshwala yinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:
(S)-(-)-2-bromo-1-α-methylbenzyl utshwala uketshezi oluphuzi olungenambala noma olukhanyayo olunephunga elikhethekile ekamelweni lokushisa. Inesakhiwo esinezinhlangothi ezintathu esigogekayo njengoba siyinhlanganisela ye-chiral okungukuthi, kunesikhungo se-chiral ku-axis ye-symmetry yamangqamuzana.

Ukusetshenziswa: Ingasetshenziswa futhi njenge-ligand yama-catalyst e-stereoelective.

Indlela:
Indlela yokulungiselela ye-(S)-(-)-2-bromo-1-α-methylbenzyl alcohol ingatholwa ngokuphendula ama-aldehydes noma ama-ketone nge-thionyl bromide ngaphansi kwezimo ze-alkali. Ngemva kokusabela kwenzeka, ukuhlukaniswa kwama-achiral compounds kanye nokuhlanzwa kwe-chiral kwama-chiral compounds kuyadingeka.

Ulwazi Lokuphepha:
Ukuthintana nesikhumba namehlo kudinga ukugwenywa.
Ngesikhathi sokusebenza, ukungena komoya okuhle kufanele kuqinisekiswe ukugwema ukuhogela noma ukungenwa.
Inhlanganisela ingabola emazingeni aphezulu okushisa ukuze ikhiqize amagesi ayingozi, okudingeka agcinwe kude nemithombo yokuthungela kanye namazinga okushisa aphezulu.
Izimpahla zokuzivikela ezifanele ezifana namagilavu ​​zelabhu nezibuko zokuphepha kufanele zigqokwe ngesikhathi sokusetshenziswa.
Izinkambiso nezinqubo zokuphepha ezifanele kufanele zilandelwe ekuphatheni nasekulahleni.
Ezisetshenziswa ezingokoqobo, izimo eziqondile kakhulu kanye nezimo zokuhlola kufanele futhi kucatshangelwe.
