Folasaga
2,5-Dibromo-3-trimethylpyridine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i nisi o ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Faʻaaliga: 2,5-Dibromo-3-trimethylpyridine o se lanu e leai se lanu samasama samasama.
- Solubility: E mafai ona fa'amavaeina i le tele o so'o so'o, pei ole ethanol, acetone, ma le dimethyl sulfoxide.
- Faʻamautu: E faʻamautu i le malamalama ma le vevela, ae mafai ona tupu le pala i lalo ole tulaga alkaline malosi.
Fa'aaogā:
- I le avea ai o se faʻamalosi: 2,5-dibromo-3-trimethylpyridine e mafai ona faʻaaogaina e fai ma sui o le brominating e faʻafefe ai nisi o gaioiga faʻasolosolo, e pei o le nucleophilic substitution, oxidation, ma condensation.
- Organic synthesis: E mafai ona faʻaaogaina e avea o se vaeluagalemu i le tuʻufaʻatasia o mea faʻapitoa, aemaise lava mo faʻalapotopotoga o loʻo i ai vaega o ketone poʻo aldehyde.
- La'au fa'aaono: E mafai fo'i ona fa'aoga ile tapenaga ole vali fa'aata.
Metotia:
I se tulaga lautele, e mafai ona saunia le 2,5-dibromo-3-trimethylpyridine e ala i le faʻaogaina o le bromine ma le bromine e avea ma mea faʻafefe i le faʻaogaina o le trimethylpyridine. E mafai ona fa'amautu tulaga fa'aalia i lea mataupu ma lea mataupu, ae tatau ona fa'aeteete mo le fa'agaioiga saogalemu.
Fa'amatalaga Saogalemu:
- 2,5-Dibromo-3-trimethylpyridine e pala i le paʻu ma mata ma e tatau ona aloese mai le faʻafesoʻotaʻi tuusaʻo.
- Fai mata puipui, totigilima ma lavalava puipui pe a fa'aoga.
- Fa'agaoi i totonu o se nofoaga e fa'afefe lelei ma aloese mai le manavaina o ona ausa.
- Aloese mai le fa'afeso'ota'i ma vaila'au fa'ama'i malolosi, e mafai ona tupu ai ni fa'alavelave mata'utia.
- E tatau ona lafoa'i otaota e tusa ai ma tulafono fa'alotoifale.
