(n-Butyl) triphenylphosphonium bromide （CAS # 1779-51-7) Gukoresha hamwe na synthesis
Butyltriphenylphosphine bromide ni urugingo rwa organofosifore. Ifite akamaro gakomeye muri synthesis, kandi dore bimwe mubisanzwe ikoreshwa hamwe nuburyo bukoreshwa:
Koresha:
1. Catalizator: Butyltriphenylphosphine bromide ikunze gukoreshwa nkumusemburo wibintu bimwe na bimwe bivura imiti. Kurugero, muri reaction ya Friedel-Gram, irashobora guhagarika reaction yo guhuza hagati ya alkine na boride kugirango ihuze isomeri ya topologiya ya alkine.
2. Chimie ya Organometallic: Butyltriphenylphosphine bromide irashobora kandi gukoreshwa nka ligand muri chimie organometallic. Irashobora gukora ibice hamwe na ion yicyuma kandi ikagira uruhare mubikorwa bimwe na bimwe byingenzi bya synthesis, nka Suzuki reaction.
Uburyo bwa Synthesis:
Hariho uburyo bwinshi bwo gusanisha butyltriphenylphosphine bromide, kandi ibikurikira nimwe muburyo busanzwe:
1. Igisubizo cyibikoresho fatizo: bromobenzene, triphenylphosifine, butane bromide;
2. Intambwe:
(1) Mu kirere kitagira inert, bromobenzene na triphenylphosifine byongewe kuri flask ya reaction;
.
(3) Buhoro buhoro ongeramo butane bromide nkuko bikenewe hanyuma ukomeze reaction ikangura;
(4) Nyuma yuko reaction irangiye, shyira ubushyuhe bwicyumba;
(5) Gukuramo no gukaraba hamwe na solge, no gukama, korohereza hamwe nizindi ntambwe zo kuvura;
(6) Hanyuma, ibicuruzwa bya butyltriphenylphosifine bromide iraboneka.
