Folasaga
3. acid pinacol ester o se fa'aputu fa'aola fa'atasi ai ma se fua fa'ama'i o le C12H19BO3 ma le mamafa mole o le 214.09g/mol.
natura:
- Fa'aaliga: Suavai e leai ni lanu po'o le malo
-Meli liusuavai:-43 ~-41 ℃
-Puna: 135-137 ℃
-Miomio: 1.05 g/mL
-Solubility: Solu i solu masani masani e pei ole dimethylformamide, dichloromethane, methanol ma ethanol.
Fa'aaogā:
- 3, acid pinacol ester o se tasi o intermediates taua i organic synthesis. E mafai ona faʻaaogaina e avea o se reagent mo le fausiaina o le C-O ma le C-C noataga, ma e masani ona faʻaaogaina e fai ma faʻamalosi mo le faʻaogaina o le C-C e pei o le Suzuki reaction ma le Stille reaction.
-E mafai foi ona faʻaogaina le faʻapipiʻi e saunia ai isi vaega galue poʻo mea faʻapipiʻi, e pei o aldehydes, ketones ma acids.
Metotia:
- 3, acid pinacol ester e masani ona saunia e ala i le tali atu Pyran ma boronic acid pinacol i lalo catalysis alkali. E mafai ona filifilia le auala sauniuni e tusa ai ma manaʻoga moni, ma o se auala masani sauniuni e aofia ai le faʻaaogaina o le sodium borate ma le pinacol e tali atu ai i lalo ole tulaga alkaline.
Fa'amatalaga Saogalemu:
3, acid pinacol ester atonu e afaina ai le soifua maloloina ma le siosiomaga. O le fa'aogaina e tatau ona mulimulita'i i fa'atonuga sa'o ile falesu'esu'e ma fa'aauupegaina i mea faigaluega mo le puipuia o le tagata lava ia, e pei o totigilima falesuesue ma le puipuiga o mata.
E le gata i lea, o fa'amatalaga fa'apitoa mo le saogalemu ma fa'atonuga fa'agaioiga e tatau ona fa'asino i le pepa fa'amaumauga o le saogalemu (SDS) po'o isi fa'amatalaga fa'atatau kemikolo.
