I-3-Fluoro-5-bromobenzyl bromide (CAS# 216755-57-6)

Isingeniso

I-3-Fluoro-5-bromobenzyl bromide iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C7H5Br2F. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:

Imvelo:

-Ukubukeka: Ayinambala ikristale ephuzi

-Indawo yokuncibilika: 48-51 ℃

-Indawo yokubilisa: 218-220 ℃

-Ukuzinza: uzinzile ngaphansi kwezimo ezomile, kodwa i-hydrolyzed phambi komswakama

-I-Solubility: Incibilika kuzincibilikisi zemvelo, njenge-ethanol, i-ether

Sebenzisa:

I-3-Fluoro-5-bromobenzyl bromide ivamise ukusetshenziswa njengendawo emaphakathi ku-organic synthesis futhi ingasetshenziselwa ukuhlanganiswa kwezinto eziphilayo ezisebenzayo, njengezidakamizwa, izibulala-zinambuzane nodayi. Ingasetshenziswa futhi njenge-ligand ukwenza ama-complexes anezinsimbi futhi idlale indima ebalulekile ekuphenduleni kwe-catalytic.

Indlela:

I-3-Fluoro-5-bromobenzyl bromide ingahlanganiswa ngezinyathelo ezilandelayo:

1. I-3-fluorobenzyl isabela nge-bromine ku-chloroform ukuze ithole i-3-fluoro-3-bromobenzyl.

2. Umkhiqizo otholwe ekuphenduleni kwangaphambilini uphendulwa nge-bromine ku-ethanol ukuze kutholwe umkhiqizo wokugcina we-3-Fluoro-5-bromobenzyl bromide.

Ulwazi Lokuphepha:

-

Lena inhlanganisela ye-alkyl enobuthi obuqinile futhi idinga ukugcinwa kahle ukuze igweme umswakama. Naka izindaba zokuphepha ezilandelayo ezisebenzayo:

- I-3-Fluoro-5-bromobenzyl bromide iyacasula futhi kufanele igweme ukuhogela igesi noma isitimu, futhi igweme ukuthinta isikhumba namehlo.

-Ngesikhathi sokusetshenziswa noma ukugcinwa, indawo enomoya omuhle kufanele igcinwe.

-Uma ubhekene nalesi sakhi, hlambulula ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo kudokotela.

-Gqoka izinto zokuzivikela ezifanele njengamagilavu ​​okuvikela amakhemikhali, izibuko nezingubo zokuzivikela ngesikhathi sokusebenza.
