| Tulaga lamatia | R22 – E afaina pe a foloina R37/38 – Fa'aitaita i le manava ma le pa'u. R41 – Tulaga lamatia o le faaleagaina mata |
| Fa'amatalaga Saogalemu | S26 – Pe a pa'i i mata, fufulu vave i le tele o vai ma saili fautuaga fa'afoma'i. S39 – Fai le puipuiga o mata/mata. |
| Vasega o Tulaga Lamatia | FAAFITAU |
Folasaga
O se mea fa'aletino fa'atasi ma le fua mole mole C≡H∞BrFN, o lo'o i ai se fa'atomu fluorine, se methyl group ma se bromine atom e sui i luga o le mama pyridine.
natura:
ose malo malosi, oona ma fa'aita. E mafai ona solu i so'o so'o e pei o le ethanol ma le dimethylformamide i le vevela o le potu, ma e mafai ona fa'apipi'i le hydrogen i nisi o mea e talia fa'amau (fa'ata'ita'iga, ava malosi).
Fa'aaogā:
E masani ona faʻaaogaina e avea o se mea amata poʻo se vaeluagalemu i faʻasologa faʻasologa o meaola. E mafai ona faʻaaogaina i le sauniuniga o vailaʻau faʻamaʻi, vailaʻau faʻamaʻi ma isi vailaʻau faʻapitoa. O le tele o fa'aoga e aofia ai su'esu'ega fa'afoma'i, fa'asologa o vaila'au ma mea fa'asaienisi.
Sauniuniga auala:
O le auala sauniuni o le fluorination e mafai ona ausia e le benzyl bromination ma le fluorination. Muamua, o le benzyl compound (4-methylpyridine) o loʻo faʻaalia ma le benzylidene bromide e maua ai le bromobenzyl compound (2-bromo-4-methylpyridine). O lenei fa'afefiloi e fa'afefeteina ma le hydrofluoric acid e maua ai le mea fa'afefete fa'atatau (phosphonium).
Fa'amatalaga Saogalemu:
e oona, e tatau ona faia ni puipuiga talafeagai. Aloese mai le fa'afeso'ota'i ma le pa'u, mata ma le manava ile taimi ole taotoga. E tatau ona fa'aoga i se nofoaga e savili lelei, ma fai matatioata puipui talafeagai, totigilima ma matapulepule. Taofi ese mai afi ma vailaʻau faʻamaʻi, ma aloese mai le tali atu i isi vailaʻau. Afai e fa'aalia pe manava, saili vave fautuaga faafoma'i.
