I-Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 ekwaziwa ngokuba yi-sodium triacetoxyhydroborate, edla ngokufinyezwa yi-STAB, yikhemikhali enefomyula i-Na(CH3COO)3BH. Njengezinye ii-borohydrides, isetyenziswa njenge-reducing agent kwi-organic synthesis. Le tyuwa ingenambala ilungiswa yi-protolysis ye-sodium borohydride ene-acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.

Ngenxa yeziphumo ze-steric neze-elektroniki zamaqela e-acetoxy, i-sodium triacetoxyborohydride yiarhente yokunciphisa ethambileyo kune-sodium borohydride okanye ne-sodium cyanoborohydride. Ngaphezu koko, i-NaBH(OAc)3 iyaziphepha iimveliso ezinobungozi eziveliswa yi-sodium cyanoborohydride. I-Sodium triacetoxyborohydride ifanelekile ngokukodwa ekunciphisweni kwe-aldehydes kunye nee-ketones.
Nangona kunjalo, ngokungafaniyo ne-sodium cyanoborohydride, i-triacetoxyborohydride ayiva manzi, kwaye amanzi awanakusetyenziselwa njengesinyibilikisi esinale reagent, kwaye ayihambelani ne-methanol. Isabela kancinci kuphela nge-ethanol kunye ne-isopropanol kwaye ingasetyenziswa kunye nazo. I-NaBH(OAc)3 ingasetyenziselwa ne-alkylation yokunciphisa i-amines yesibini kunye ne-aldehyde-bisulfite adducts.
