Pyridine-4-boronic acid (CAS # 1692-15-5) kenyelletso
4-Pyridine boronic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 4-pyridine boronic acid:
Boleng:
- Ponahalo: 4-pyridine boronic acid ke kristale e se nang 'mala e tiileng.
- Solubility: E qhibiliha ka metsing le ka har'a litlhare tse tloaelehileng tse kang joala, ethers le ketone.
- Botsitso: 4-Pyridine boronic acid e tsitsitse mocheso oa kamore, empa ho senyeha ho ka 'na ha etsahala ka ho ba teng ha mocheso o phahameng, khatello e phahameng, kapa li-oxidants tse matla.
Sebelisa:
- Catalyst: 4-pyridylboronic acid e ka sebelisoa e le sesosa sa karabelo ea organic synthesis, joalo ka karabelo ea CC bond le karabelo ea oxidation.
- Coordination reagent: E na le liathomo tsa boron, 'me 4-pyridylboronic acid e ka sebelisoa e le mokhoa oa ho kopanya li-ion tsa tšepe, e bapala karolo ea bohlokoa ho catalysis le lik'hemik'hale tse ling tsa lik'hemik'hale.
Mokhoa:
- 4-Pyridine boronic acid e ka fumanoa ka ho itšoara ka 4-pyridone ka boric acid. Maemo a ikhethileng a karabelo a tla fetoloa ho latela maemo a nnete.
Lintlha tsa Tšireletseho:
- 4-Pyridine boronic acid ke motsoako o akaretsang oa lintho tse phelang, empa ho ntse ho hlokahala hore u hlokomele ho sebetsana ka mokhoa o sireletsehileng. Likhalase tse sireletsang le liatlana li lokela ho apesoa bakeng sa ts'ebetso.
- Qoba ho kopana le letlalo le ho hema lerōle. Tabeng ea ho kopana le letlalo ka phoso, hlatsoa hang-hang ka metsi a mangata.
- Nakong ea tšebeliso le polokelo, tlhokomelo e lokela ho nkoa ho qoba ho kopana le li-oxidants tse matla le li-acids tse matla ho qoba ho baka liketso tse kotsi.
- Ha ho lahla litšila, ho lokela ho lahloa ka mokhoa o sireletsehileng ho latela melao ea sebaka seo.
