Pyridine-4-boronic acid (CAS # 1692-15-5) folasaga
4-Pyridine boronic acid o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 4-pyridine boronic acid:
Tulaga lelei:
- Fa'aaliga: 4-pyridine boronic acid ose ma'a tioata e leai ni lanu.
- Soluble: Solu i le vai ma solu fa'aola masani e pei ole ava malosi, ethers, ma ketones.
- Faʻamautu: 4-Pyridine boronic acid e mautu i le vevela o le potu, ae mafai ona faʻaleagaina pe a iai le maualuga o le vevela, mamafa maualuga, poʻo le malosi o le oxidants.
Fa'aaogā:
- Catalyst: 4-pyridylboronic acid e mafai ona faʻaaogaina e fai ma faʻamalosi i gaioiga faʻapipiʻi faʻasolosolo, e pei o le CC bond formation reactions ma oxidation reactions.
- Coordination reagent: O loʻo i ai boron atoms, ma le 4-pyridylboronic acid e mafai ona faʻaaogaina e avea o se faʻamaopoopo faʻamaopoopo mo ion uʻamea, e taʻalo ai se sao taua i le catalysis ma isi gaioiga faʻamaʻi.
Metotia:
- 4-Pyridine boronic acid e mafai ona maua e ala i le taliina o le 4-pyridone ma le boric acid. O tulaga faʻapitoa faʻaalia o le a fetuunai e tusa ai ma le tulaga moni.
Fa'amatalaga Saogalemu:
- 4-Pyridine boronic acid o se faʻalapotopotoga masani masani, ae e manaʻomia pea le tausia lelei o le taulimaina. Matatioata puipui ma totigilima e tatau ona ofuina mo le taotoga.
- Aloese mai le fa'afeso'ota'i ma le pa'u ma le manava o le pefu. A fa'afuase'i ona pa'i i le pa'u, fufulu vave i le tele o vai.
- A'o fa'aoga ma teuina, e tatau ona fa'aeteete ina ia 'alofia le fa'afeso'ota'i ma vaila'au malolosi ma vaila'au malolosi e 'alofia ai le fa'atupuina o fa'alavelave mata'utia.
- Pe a lafoai otaota, e tatau ona lafoai ma le saogalemu e tusa ai ma tulafono faatonutonu a le lotoifale.
