Kev Nyab Xeeb Kev Nyab Xeeb Case 56553-60-7 hmoov sodium triacetoxyborohydride
Khoom npe: sodium triacetoxyborohydride
CAS: 56553-60-7
Molecular Cov Qauv: C6h10BNNOO6
Zog: Cov hmoov dawb dawb
Cov ntsiab lus: 95.0% ~ 105.0% (Kaum Tes)
Siv: Rau kev ua haujlwm txo cov tshuaj tiv thaiv ntawm Ketone thiab Aldehyde, redamization ntawm carbonyl compound thiab amine, thiab reductive amination ntawm aryl aldehyde
Muaj peev xwm: 5 ~ 10mmt / hli
Sodium triacetoxyborohybride (stab) CAS 56553-60-7, feem ntau yog cov tshuaj lom neeg nrog cov qauv ntawm na (Ch3Coo) 3bh. Zoo li lwm cov neeg ua haujlwm, nws yog siv los ua tus neeg sawv cev txo qis hauv cov xwm txheej hauv cov organic. Cov ntsev tsis muaj xim yog npaj los ntawm cov sodium borohydride nrog acetic acid: Nabh4 + 3 Ho2Cch3 → Nabh (O2CCH3) 3 + 3 H2.
Txawm li cas los xij, tsis zoo li sodium cyanoborohydride, lub triacetoxyborohydride, tsis tuaj yeem siv los ua cov kuab tshuaj nrog cov reagent no, tsis yog nws sib xws nrog Methanol. Nws reacts tsuas maj mam nrog ethanol thiab isopropanol thiab tuaj yeem siv nrog cov no. Nabh (OAC) 3 kuj tseem siv tau rau kev rov kho dua Alkylation ntawm cov qib nrab ntawm cov aldehyde-bisulfite adductions.
