Nhanganyaya
2,5-Difluorobromobenzene is an organic compound. Iyi inotevera sumo yakadzama kune yayo zvivakwa, mashandisiro, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
2,5-Difluorobromobenzene imvura isina ruvara uye ine hwema hwakasiyana. Haina kunyungudika mumvura asi inonyungudika muorganic solvents senge madoro, ether, uye ketone.
Shandisa:
2,5-Difluorobromobenzene inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis. Inogonawo kushandiswa se ligand ye organometallic catalysts uye inoshandiswa mukutsiva maitiro, coupling reactions, nezvimwewo mune organic synthesis reactions.
Nzira:
Nzira yekugadzirira ye2,5-difluorobromobenzene yakaoma uye inogona kugadzirwa nemaitiro anotevera:
Pamberi pebromobenzene, cuprous bromide uye difluoromethanesulfonamide zvinoitwa pamberi pebromobenzene kugadzira 2,5-difluorobromobenzene.
Phenylmagnesium bromide inobatwa ne cuprous fluoride kugadzira 2,5-diphenyldifluoroethane, iyo inobva yaiswa pasi pebromination uye iodination reactions kuti iwane 2,5-difluorobromobenzene.
Zvekuchengetedza
2,5-Difluorobromobenzene inogumbura uye inogona kukonzera kusagadzikana kuburikidza nekufema, kubata ganda, kana kutarisana neziso. Kuratidzwa kwakananga paganda nemeso kunofanirwa kudzivirirwa panguva yekubata, uye midziyo yekudzivirira senge magirovhosi ekudzivirira uye magirazi anofanira kupfekwa kana zvichidikanwa. Mukugadzirira nekushandisa, kutarisisa kunofanirwa kubhadharwa kukudzivirira kwemoto uye kuputika, uye kuve nechokwadi chekufefetera kwakanaka. Paunenge uchishandisa nekuchengetedza, 2,5-difluorobromobenzene inofanira kuchengetwa pahutano hwakakodzera uye mumudziyo wakavharwa, kure nekupisa, kupisa uye oxidants.
