Folasaga
2,5-Difluorobromobenzene o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga auiliili i ona meatotino, faʻaoga, auala gaosiga ma faʻamatalaga saogalemu:
Tulaga lelei:
2,5-Difluorobromobenzene o se vai e leai ni lanu ma se manogi uiga ese. E le mafai ona solu i totonu o le vai ae e mafai ona solu i solu faʻaletino e pei ole ava malosi, eter, ma ketones.
Fa'aaogā:
2,5-Difluorobromobenzene e masani ona faʻaaogaina e avea o se mea taua tele i le faʻaogaina o meaola. E mafai foʻi ona faʻaaogaina e avea o se ligand mo organometallic catalysts ma faʻaaogaina i mea e suitulaga ai, faʻafesoʻotaʻi tali, ma isi i faʻasologa faʻasolosolo faʻasolosolo.
Metotia:
Ole auala sauniuni ole 2,5-difluorobromobenzene e faʻalavelave ma e masani ona faʻapipiʻiina e ala i tali nei:
I le i ai o le bromobenzene, cuprous bromide ma le difluoromethanesulfonamide o loʻo faʻaalia i luma o le bromobenzene e maua ai le 2,5-difluorobromobenzene.
O le Phenylmagnesium bromide e faʻafefe i le cuprous fluoride e faʻatupu ai le 2,5-diphenyldifluoroethane, lea e tuʻuina atu i le bromination ma le iodination reactions e maua ai le 2,5-difluorobromobenzene.
Fa'amatalaga Saogalemu:
2,5-Difluorobromobenzene e faʻafefe ma e mafai ona mafua ai le faʻalavelave e ala i le manava, paʻu paʻu, poʻo le vaʻaia o mata. E tatau ona 'alofia le fa'aalia sa'o i le pa'u ma mata i le taimi o feso'ota'iga, ma e tatau ona ofuina mea e puipui ai le tagata lava ia e pei o totigilima ma mata tioata pe a mana'omia. I sauniuniga ma le faʻaogaina, e tatau ona gauai atu i le afi ma le pa, ma faʻamautinoa tulaga lelei o le ea. Pe a faʻaaogaina ma teuina, 2,5-difluorobromobenzene e tatau ona teuina i se vevela talafeagai ma i totonu o se pusa faʻamaufaʻailoga, ese mai le faʻamalama, vevela ma mea faʻamaʻi.
