Habka dhoofinta badbaadada leh CAS 56553-60-7 budada Sodium triacetoxyborohydride
Magaca alaabta: Sodium triacetoxyborohydride
CAS:56553-60-7
Qaaciddada molecular:C6H10BNaO6
Muuqaal: budo cad
Waxa ku jira: 95.0% ~ 105.0% (titration)
Waxay isticmaashaa: Si loo yareeyo falcelinta ketone iyo aldehyde, amine-ka-yaraynta ama lactamization of compound carbonyl iyo amine, iyo hoos u dhigista amination ee aryl aldehyde
Awoodda: 5 ~ 10mt / bishii
Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 sidoo kale loo yaqaan sodium triacetoxyhydroborate, oo inta badan loo soo gaabiyo STAB, waa iskudhis kiimiko ah oo leh caanaha Na (CH3COO) 3BH.Si la mid ah borohydrides kale, waxaa loo isticmaalaa sidii wakiilka yaraynta ee isku-dhafka organic.Cusbadaan aan midabka lahayn waxaa lagu diyaariyaa protonolysis of sodium borohydride oo leh acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Si kastaba ha ahaatee, si ka duwan sodium cyanoborohydride, triacetoxyborohydride waa biyo-xasaasi ah, biyahana looma isticmaali karo sida dareere leh reagent-kan, mana la jaan qaadi karo methanol.Waxay si tartiib tartiib ah ula falgashaa ethanol iyo isopropanol waxaana loo isticmaali karaa kuwan.NaBH(OAc)3 waxa kale oo loo isticmaali karaa alkylation-ka yaraynta aminyada sare ee aldehyde-bisulfite.
