Gabatarwa
2,5-Difluorobromobenzene wani fili ne na kwayoyin halitta. Mai zuwa shine cikakken gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:
inganci:
2,5-Difluorobromobenzene ruwa ne mara launi tare da wari na musamman. Yana da rashin narkewa a cikin ruwa amma yana narkewa a cikin kaushi na halitta kamar su alcohols, ethers, da ketones.
Amfani:
2,5-Difluorobromobenzene ana amfani dashi akai-akai azaman tsaka-tsaki mai mahimmanci a cikin ƙwayoyin halitta. Hakanan za'a iya amfani dashi azaman ligand don masu haɓaka organometallic kuma ana amfani dashi a cikin maye gurbin halayen, halayen haɗuwa, da sauransu.
Hanya:
Hanyar shiri na 2,5-difluorobromobenzene yana da rikitarwa kuma yawanci ana iya haɗa shi ta hanyar halayen masu zuwa:
A gaban bromobenzene, cuprous bromide da difluoromethanesulfonamide suna amsawa a gaban bromobenzene don samar da 2,5-difluorobromobenzene.
Phenylmagnesium bromide yana amsawa tare da fluoride na cuprous don samar da 2,5-diphenyldifluoroethane, wanda aka sanya shi zuwa bromination da iodination halayen don samun 2,5-difluorobromobenzene.
Bayanin Tsaro:
2,5-Difluorobromobenzene yana da haushi kuma yana iya haifar da rashin jin daɗi ta hanyar inhalation, hulɗar fata, ko ido ido. Ya kamata a nisanta kai tsaye ga fata da idanu yayin saduwa, kuma yakamata a sanya kayan kariya na sirri kamar safar hannu da tabarau na kariya idan ya cancanta.
