(n-Butyl)triphenylphosphonium bromide（CAS# 1779-51-7)Whakamahinga me nga tikanga whakahiato
Ko te butyltriphenylphosphine bromide he pūhui organophosphorus. He nui nga tono mo te whakahiato waro, a, koinei etahi o ana whakamahinga noa me nga tikanga whakahiato:
Whakamahia:
1. Catalyst: Ko te butyltriphenylphosphine bromide te nuinga o te whakamahi hei whakakorikori mo etahi tauhohenga matū. Hei tauira, i roto i te tauhohenga Friedel-Gram, ka taea e ia te whakakorikori i te tauhohenga hono i waenga i nga alkynes me nga borides ki te whakahiato i nga iota topological o alkynes.
2. Te matū organometallic: Ka taea hoki te whakamahi butyltriphenylphosphine bromide hei ligand i roto i te matū organometallic. Ka taea e ia te hanga matatini me nga katote whakarewa me te whai waahi ki etahi tauhohenga whakahiato waro nui, penei i te tauhohenga a Suzuki.
Tikanga whakahiato:
He maha nga tikanga mo te whakahiato o te butyltriphenylphosphine bromide, a ko enei e whai ake nei tetahi o nga tikanga noa:
1. Tauhohenga rauemi mata: bromobenzene, triphenylphosphine, butane bromide;
2. Hipanga:
(1) I roto i te hau hau, ka taapirihia te bromobenzene me te triphenylphosphine ki te ipu hohenga;
(2) Ka hirihia te pounamu hohenga me te oho i raro i te mana o te pāmahana, a, ko te 60-80 nga nekehanga Celsius te pāmahana tauhohenga whānui;
(3) Taapirihia te butana bromide ina hiahiatia ka haere tonu te whakaohooho;
(4) Kia oti te tauhohenga, whakamatao ki te pāmahana rūma;
(5) Te tangohanga me te horoi ki nga whakarewa, me te whakamaroke, te whakamaroke me etahi atu waahanga maimoatanga;
(6) Ka mutu, ka whiwhi hua butyltriphenylphosphine bromide.
