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

(S)-(-)-2-bromo-1-α-methylbenzyl utywala yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

Umgangatho:
(S)-(-)-2-bromo-1-α-methylbenzyl utywala lulwelo olungenambala okanye olukhanyayo olutyheli kunye nevumba elikhethekileyo kwiqondo lokushisa. Inokwakheka kwe-dimensional enokukhubazeka okuthathu njengoko iyikhompawundi ye-chiral okt, kukho iziko le-chiral kwi-axis ye-molecular symmetry.

Ukusetyenziswa: Isenokusetyenziswa njenge-ligand ye-stereoelective catalysts.

Indlela:
Indlela yokulungiselela (S) - (-) -2-bromo-1-α-methylbenzyl utywala inokufumaneka ngokuphendula i-aldehydes okanye i-ketones kunye ne-thionyl bromide phantsi kweemeko ze-alkaline. Emva kokuphendula kwenzeka, ukuhlukaniswa kwe-achiral compounds kunye nokuhlanjululwa kwe-chiral ye-chiral compounds kuyadingeka.

Ulwazi ngoKhuseleko:
Ukudibana nolusu kunye namehlo kufuneka kuphetshwe.
Ngexesha lokusebenza, umoya ococekileyo kufuneka uqinisekiswe ukuphepha ukuphefumla okanye ukungena.
Ikhompawundi inokubola kumaqondo obushushu aphezulu ukuvelisa iigesi eziyingozi, ekufuneka zigcinwe kude nemithombo yokutshisa kunye namaqondo obushushu aphezulu.
Izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu zelebhu kunye neglasi zokhuseleko kufuneka zinxitywe ngexesha lokusetyenziswa.
Imilinganiselo yokhuseleko olufanelekileyo kunye neenkqubo kufuneka zilandelwe ekuphatheni nasekulahlweni.
Kwizicelo ezisebenzayo, iimeko ezithe ngqo ngakumbi kunye neemeko zovavanyo kufuneka kwakhona zithathelwe ingqalelo.
