Isingeniso
I-2,5-Difluorobromobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esinemininingwane yezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-2,5-Difluorobromobenzene iwuketshezi olungenambala olunephunga elingavamile. Ayincibiliki kahle emanzini kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, nama-ketone.
Sebenzisa:
I-2,5-Difluorobromobenzene ivamise ukusetshenziswa njengento ebalulekile emaphakathi ekuhlanganiseni kwe-organic. Ingasetshenziswa futhi njenge-ligand yama-catalysts e-organometallic futhi isetshenziswe ekuphenduleni esikhundleni, ukusabela okuhlangene, njll. ekuphenduleni kwe-organic synthesis.
Indlela:
Indlela yokulungiselela ye-2,5-difluorobromobenzene iyinkimbinkimbi futhi ngokuvamile ingahlanganiswa ngokusabela okulandelayo:
Lapho kukhona i-bromobenzene, i-cuprous bromide ne-difluoromethanesulfonamide ziyasabela lapho kukhona i-bromobenzene ukukhiqiza i-2,5-difluorobromobenzene.
I-Phenylmagnesium bromide isabela nge-curous fluoride ukuze ikhiqize i-2,5-diphenyldifluoroethane, ebese ifakwa ngaphansi kwe-bromination kanye nokusabela kwe-iodination ukuze kutholwe i-2,5-difluorobromobenzene.
Ulwazi Lokuphepha:
I-2,5-Difluorobromobenzene iyacasula futhi ingabangela ukungakhululeki ngokuhogela, ukuthintana kwesikhumba, noma ngokuthinta amehlo. Ukuchayeka okuqondile esikhumbeni nasemehlweni kufanele kugwenywe ngesikhathi sokuxhumana, futhi izinto zokuzivikela ezifana namagilavu okuzivikela kanye nezibuko kufanele zigqokwe uma kunesidingo. Ekulungiseni nasekusetshenzisweni, kufanele kuqashelwe ukuvimbela umlilo nokuqhuma, futhi kuqinisekiswe izimo ezinhle zokungenisa umoya. Uma usebenzisa futhi ugcina, i-2,5-difluorobromobenzene kufanele igcinwe ezingeni lokushisa elifanele futhi esitsheni esivaliwe, kude nokushisa, ukushisa kanye nama-oxidants.
