I-Pyridine-4-boronic acid (i-CAS # 1692-15-5) intshayelelo
I-4-Pyridine boronic acid yi-organic compound. Oku kulandelayo kukwaziswa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-4-pyridine boronic acid:
Umgangatho:
- Imbonakalo: I-4-pyridine boronic acid yinto eqinileyo yecrystalline engenambala.
-Ukunyibilika: Inyibilika emanzini kunye nezinyibilikisi eziqhelekileyo zendalo ezifana neealkoholi, ii-ethers, kunye neeketones.
- Ukuzinza: I-4-Pyridine boronic acid izinzile kwiqondo lokushisa, kodwa ukubola kungenzeka xa kukho ukushisa okuphezulu, uxinzelelo oluphezulu, okanye i-oxidants enamandla.
Sebenzisa:
- I-Catalyst: I-4-pyridylboronic acid ingasetyenziselwa njenge-catalyst kwi-organic synthesis reactions, njenge-CC yokubunjwa kwebhondi kunye neempendulo ze-oxidation.
- Ulungelelwaniso lwe-reagent: Iqukethe i-athomu ye-boron, kunye ne-4-pyridylboronic acid ingasetyenziselwa njenge-reagent yokulungelelanisa i-ion yensimbi, idlala indima ebalulekileyo kwi-catalysis kunye nezinye iikhemikhali.
Indlela:
- I-4-Pyridine boronic acid inokufumaneka ngokuphendula i-4-pyridone nge-boric acid. Iimeko ezithile zokusabela ziya kulungelelaniswa ngokweyona meko.
Ulwazi ngoKhuseleko:
- I-4-Pyridine boronic acid yi-compound ye-organic organic, kodwa kusafuneka ukuba unakekele ukuphatha ngokukhuselekileyo. Iiglasi ezikhuselayo kunye neeglavu kufuneka zinxitywe xa zisebenza.
- Kuphephe ukudibana nolusu kunye nokuphefumla uthuli. Kwimeko yokudibanisa ngengozi nesikhumba, hlambulula ngokukhawuleza ngamanzi amaninzi.
- Ngexesha lokusetyenziswa kunye nokugcinwa, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa nee-oxidants ezinamandla kunye ne-acids eqinile ukuze ugweme ukubangela ukuphendula okuyingozi.
- Xa ulahla inkunkuma, kufuneka ilahlwe ngokukhuselekileyo ngokuhambelana nemimiselo yendawo.
