Pyridine-4-acide boronic （CAS # 1692-15-5) intangiriro
4-Acide ya pyridine boronic ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 4-pyridine boronic aside:
Ubwiza:
- Kugaragara: 4-pyridine boronic aside ni kirisiti itagira ibara.
- Gukemura: Kubora mumazi hamwe nibisanzwe kama nka alcool, ethers, na ketone.
- Igihagararo: 4-Pyridine boronic aside ihagaze neza mubushyuhe bwicyumba, ariko kubora bishobora kubaho mugihe hari ubushyuhe bwinshi, umuvuduko mwinshi, cyangwa okiside ikomeye.
Koresha:
.
- Guhuza reagent: Irimo atome ya boron, na acide 4-pyridylboronic irashobora gukoreshwa nka reagent ya reagent ya ioni yicyuma, ikagira uruhare runini muri catalizike nubundi buryo bwa chimique.
Uburyo:
- 4-Pyridine boronic aside irashobora kuboneka mugukora 4-pyridone hamwe na aside ya boric. Imiterere yihariye yo kwitwara izahindurwa ukurikije uko ibintu bimeze.
Amakuru yumutekano:
- 4-Pyridine boronic aside ni uruganda rusange, ariko biracyakenewe kwitabwaho neza. Ibirahuri bikingira hamwe na gants bigomba kwambara kugirango bikore.
- Irinde guhura nuruhu no guhumeka umukungugu. Mugihe uhuye nimpanuka nimpu, kwoza ako kanya n'amazi menshi.
- Mugihe cyo gukoresha no kubika, hagomba kwitonderwa kugirango wirinde guhura na okiside ikomeye na acide zikomeye kugirango wirinde gutera ingaruka mbi.
- Iyo guta imyanda, bigomba kujugunywa neza hakurikijwe amategeko yaho.
