Folasaga
O le 2,4-difluorobenzylbromide ose fa'aputuga fa'aola fa'atasi ma le fua fa'ama'i C7H5BrF2. O se vai e le lanu ma se manogi malosi. O loʻo taua i lalo se faʻamatalaga o nisi o meatotino, faʻaoga, metotia ma faʻamatalaga saogalemu o le 2,4-difluorobenzylbromide:
natura:
-Fa'aaliga: 2,4-difluorobenzylbromide o se vai e leai ni lanu.
-Solubility: E mafai ona soluble i solu faʻalaʻau, pei ole ethanol, chloroform ma dimethylformamide.
Fa'aaogā:
-2,4-difluorobenzylbromide e mafai ona faʻaaogaina e avea o se vaeluagalemu i le faʻaogaina o meaola ma faʻaaogaina i le tuʻufaʻatasia o isi mea faʻapipiʻi.
-E mafai foi ona faʻaaogaina e avea o se mea mataʻutia i le fanua o vailaau faʻasaina ma vailaʻau.
Metotia:
-2,4-difluorobenzylbromide e masani ona saunia e ala i le tali atu i le 2,4-difluorobenzoic acid ma le bromine.
-O le auala sauniuni faapitoa e mafai ona fetuunai tulaga tali ma reagents faʻaaogaina pe a manaʻomia.
Fa'amatalaga Saogalemu:
- 2,4-difluorobenzylbromide e faʻafefe ma manaʻomia le gauai atu i faiga puipuia e pei o le ofuina o totigilima ma lavalava puipui.
- Aloese mai le manava, faʻafesoʻotaʻi ma le paʻu ma mata aʻo faʻaaogaina.
-I le tulaga o le manava faʻafuaseʻi poʻo le faʻalavelave faʻafuaseʻi, o le tagata ua aʻafia e tatau ona vave faʻanofo i se ea fou ma togafitia i togafitiga faafomaʻi.
-Pe a teuina, taofi le 2,4-difluorobenzylbromide mai le afi ma le oxidant e aloese ai mai le lamatiaga o le afi ma le pa.
