Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 izwi kandi nka sodium triacetoxyhydroborate, ikunze kuvugwa muri STAB mu magambo ahinnye, ni ikinyabutabire gifite formula Na (CH3COO) 3BH. Kimwe n'izindi borohydride, ikoreshwa nk'ikintu kigabanya ubukana mu gukora organic synthesis. Uyu munyu udafite ibara utegurwa binyuze muri protolysis ya sodium borohydride hamwe na aside asetiki: NaBH4 + 3 HO2CCH3 → NaBH (O2CCH3)3 + 3 H2.

Bitewe n'ingaruka za steric na elegitoroniki z'amatsinda ya acetoxy, sodium triacetoxyborohydride ni ikintu kigabanya ubukana kurusha sodium borohydride cyangwa sodium cyanoborohydride. Byongeye kandi, NaBH (OAc)3 yirinda ibintu bibi bivamo sodium cyanoborohydride. Sodium triacetoxyborohydride ikwiriye cyane cyane mu kugabanya aldehydes na ketones.
Ariko, bitandukanye na cyanoborohydride ya sodium, triacetoxyborohydride ntishobora kwangirika ku mazi, kandi amazi ntashobora gukoreshwa nk'umusemburo hamwe n'iyi reagent, kandi ntabwo ihuye na methanol. Ikora buhoro buhoro hamwe na ethanol na isopropanol kandi ishobora gukoreshwa hamwe na byo. NaBH (OAc)3 ishobora kandi gukoreshwa mu kugabanya alkylation ya amines za kabiri hamwe na aldehyde-bisulfite adducts.
