(n-Butyl) triphenylphosphonium bromide (CAS# 1779-51-7) Mashandisirwo uye nzira dzekubatanidza
Butyltriphenylphosphine bromide inhengo ye organophosphorus. Iyo ine yakakosha maapplication mune organic synthesis, uye heano mamwe eyakajairwa kushandiswa kwayo uye nzira dzekubatanidza:
Shandisa:
1. Catalyst: Butyltriphenylphosphine bromide inowanzoshandiswa sechinhu chinokonzera mamwe maitiro emakemikari. Semuenzaniso, muFriedel-Gram reaction, inogona kukonzeresa maitiro ekubatanidza pakati pealkynes uye borides kuti igadzire topological isomers yealkynes.
2. Organometallic chemistry: Butyltriphenylphosphine bromide inogonawo kushandiswa se ligand mu organometallic chemistry. Inogona kugadzira macomplexes ane simbi ions uye kutora chikamu mune akakosha organic synthesis maitiro, akadai seSuzuki reaction.
Synthesis Method:
Pane nzira dzakati wandei dzekugadzira butyltriphenylphosphine bromide, uye inotevera ndeimwe yenzira dzakajairika:
1. Rection raw materials: bromobenzene, triphenylphosphine, butane bromide;
2. Matanho:
(1) Mumhepo inert, bromobenzene uye triphenylphosphine inowedzerwa kune reaction flask;
(2) Bhodhoro rekuita rinonamwa uye rinosimudzwa pasi pekutonga kwekushisa, uye general reaction tembiricha i60-80 degrees Celsius;
(3) Zvishoma nezvishoma wedzera butane bromide sezvinodiwa uye enderera mberi nekuita ichikurudzira;
(4) Pashure pekuita kwapera, inotonhorera kusvika kune imwe tembiricha;
(5) Kubvisa uye kugeza nezvinonyungudutsa, uye kuomesa, crystallization uye mamwe matanho ekurapa;
(6) Pakupedzisira, butyltriphenylphosphine bromide chigadzirwa chinowanikwa.
