Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 izwi kandi nka sodium triacetoxyhydroborate, ikunze kwitwa STAB, ni imiti ivanze na formula Na (CH3COO) 3BH.Kimwe nizindi borohydride, ikoreshwa nkibintu bigabanya synthesis.Uyu munyu utagira ibara utegurwa na protonolysis ya sodium borohydride hamwe na acide acike: NaBH4 + 3 HO2CCH3 → NaBH (O2CCH3) 3 + 3 H2.

Bitewe n'ingaruka zidasanzwe hamwe na elegitoronike yitsinda rya acetoxy, sodium triacetoxyborohydride nigikoresho cyoroheje kigabanya sodium borohydride cyangwa na sodium cyanoborohydride.Byongeye kandi, NaBH (OAc) 3 irinda ibicuruzwa byangiza uburozi biterwa na sodium cyanoborohydride.Sodium triacetoxyborohydride irakwiriye cyane cyane kugabanya aminide ya aldehydes na ketone.
Ariko, bitandukanye na sodium cyanoborohydride, triacetoxyborohydride yorohereza amazi, kandi amazi ntashobora gukoreshwa nkumuti hamwe niyi reagent, ntanubwo bihuye na methanol.Ifata buhoro buhoro hamwe na Ethanol na isopropanol kandi irashobora gukoreshwa nibi.NaBH (OAc) 3 irashobora kandi gukoreshwa muguhindura alkylation ya amine ya kabiri hamwe na aldehyde-bisulfite.
