(n-Butyl) triphenylphosphonium bromide (CAS # 1779-51-7) Awọn lilo ati awọn ọna iṣelọpọ
Butyltriphenylphosphine bromide jẹ agbo organophosphorus. O ni awọn ohun elo pataki ni iṣelọpọ Organic, ati pe eyi ni diẹ ninu awọn lilo ti o wọpọ ati awọn ọna iṣelọpọ:
Lo:
1. ayase: Butyltriphenylphosphine bromide ni a maa n lo bi ayase fun awọn aati kemikali kan. Fun apẹẹrẹ, ninu iṣesi Friedel-Gram, o le ṣe itusilẹ iṣesi idapọ laarin alkynes ati borides lati ṣapọpọ awọn isomers topological ti alkynes.
2. Kemistri Organometallic: Butyltriphenylphosphine bromide tun le ṣee lo bi ligand ninu kemistri organometallic. O le ṣe awọn eka pẹlu awọn ions irin ati kopa ninu diẹ ninu awọn aati iṣelọpọ Organic pataki, gẹgẹbi iṣe Suzuki.
Ọna Isọpọ:
Awọn ọna pupọ lo wa fun iṣelọpọ ti butyltriphenylphosphine bromide, ati pe atẹle jẹ ọkan ninu awọn ọna ti o wọpọ:
1. Awọn ohun elo aise: bromobenzene, triphenylphosphine, butane bromide;
2. Igbesẹ:
(1) Ni oju-aye inert, bromobenzene ati triphenylphosphine ti wa ni afikun si apọn ifasilẹ;
(2) Igo ifasilẹ ti wa ni edidi ati ki o ru labẹ iṣakoso iwọn otutu, ati iwọn otutu ifarabalẹ gbogbogbo jẹ 60-80 iwọn Celsius;
(3) Laiyara ṣafikun butane bromide bi o ṣe nilo ki o tẹsiwaju aruwo;
(4) Lẹhin ti iṣesi ti pari, dara si iwọn otutu yara;
(5) Iyọkuro ati fifọ pẹlu awọn ohun elo, ati gbigbe, crystallization ati awọn igbesẹ itọju miiran;
(6) Nikẹhin, ọja bromide butyltriphenylphosphine ti gba.
