Folasaga
2,5-Difluorobenzyl bromide. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:
Tulaga lelei:
Faʻaaliga: 2,5-benzyl difluorobromide o se vai e leai se lanu poʻo sina samasama samasama.
Malosi: 1.74-1.76 g/cm³.
Soluble: Solu i solu fa'alela'au pei ole ava malosi, ethers ma non-polar solvents.
Fa'aaogā:
2,5-difluorobenzyl bromide e masani ona faʻaaogaina e avea o se mea faʻapipiʻi ma mea mataʻutia i le faʻaogaina o meaola.
I le faʻaogaina o meaola, e masani ona faʻaaogaina mo le faʻafefe o olefins ma le filifilia o le fluorination o mea manogi.
Metotia:
O le sauniuniga o le 2,5-difluorobenzyl bromide e mafai ona faia i laasaga nei:
Muamua, o le 2,5-dibromobenzyl ma le trifluoroacetic acid o loʻo faʻaalia ma faʻafefe i totonu o se kasa condensate poʻo se vai e saunia ai le vaifofo 2,5-difluorobenzylbromide.
O le oloa mama 2,5-difluorobenzyl bromide e faʻamago, faʻamama, ma faʻagogo.
Fa'amatalaga Saogalemu:
O le 2,5-difluorobenzyl bromide e iai ni mea oona, ma e tatau ona faia ni puipuiga mo le saogalemu pe a faʻaaogaina, aloese mai le faʻafesoʻotaʻi ma le paʻu, mata ma le manava.
A'o fa'aoga ma tapenapena, e tatau ona tu'uina atu mea faigaluega puipuia e pei o totigilima su'esu'e, mata tioata, ma matapulepule puipui.
E tatau ona fa'agaioia i totonu o se nofoaga e fa'afefe lelei ma aloese mai le fa'afeso'ota'i ma puna fa'amumu ma oxidants.
Pe a teuina, 2,5-difluorobenzyl bromide e tatau ona teuina i se nofoaga malulu, mago ma faʻafefe, ese mai afi ma mu.
Fa'amolemole mulimuli i fa'ata'ita'iga sa'o ile falesu'esu'e ma ta'iala saogalemu ile fa'aogaina ma le tagofiaina ole 2,5-difluorobenzyl bromide.
