(n-Butyl) triphenylphosphonium bromide (CAS# 1779-51-7) Ukusetyenziswa kunye neendlela zokudibanisa
I-butyltriphenylphosphine bromide yi-organophosphorus compound. Inezicelo ezibalulekileyo kwi-organic synthesis, kwaye nantsi enye yokusetyenziswa kwayo okuqhelekileyo kunye neendlela zokudibanisa:
Sebenzisa:
1. I-Catalyst: I-butyltriphenylphosphine bromide isetyenziswa ngokuqhelekileyo njenge-catalyst ye-chemical reactions. Ngokomzekelo, kwi-reaction ye-Friedel-Gram, inokubangela ukusabela kokudibanisa phakathi kwe-alkynes kunye ne-borides ukudibanisa i-isomers ye-topological ye-alkynes.
2. I-Organometallic chemistry: I-Butyltriphenylphosphine bromide ingasetyenziselwa njenge-ligand kwi-organometallic chemistry. Inokwenza ii-complexes ngee-ion zetsimbi kwaye ithathe inxaxheba kwezinye izinto ezibalulekileyo ze-organic synthesis reactions, ezifana ne-Suzuki reaction.
Indlela yokudibanisa:
Kukho iindlela ezininzi zokwenziwa kwe-butyltriphenylphosphine bromide, kwaye ezi zilandelayo zezinye zeendlela eziqhelekileyo:
1. Imathiriyeli ekrwada yokusabela: i-bromobenzene, i-triphenylphosphine, i-butane bromide;
2. Amanyathelo:
(1) Kwi-atmosphere engasebenziyo, i-bromobenzene kunye ne-triphenylphosphine zongezwa kwi-reaction flask;
(2) Ibhotile yokusabela itywinwe kwaye ishukunyiswe phantsi kolawulo lobushushu, kwaye ubushushu bokusabela ngokubanzi ngama-60-80 degrees Celsius;
(3) Kancinci wongeza i-butane bromide njengoko kufuneka kwaye uqhubeke nokuphendula ukuvuselela;
(4) Emva kokuba i-reaction igqityiwe, ipholile kwiqondo lokushisa;
(5) Ukukhutshwa kunye nokuhlamba ngee-solvents, kunye nokomisa, i-crystallization kunye namanye amanyathelo onyango;
(6) Ekugqibeleni, imveliso ye-butyltriphenylphosphine bromide ifunyenwe.
