Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 also known as sodium triacetoxyhydroborate, commonly abbreviated STAB, is a chemical compound with the formula Na(CH3COO)3BH. Njengayenye i-borohydrides, isetyenziswa njengearhente yokunciphisa kwi-ornthesic synthesis. Le ityuwa engenamabala ilungiselelwe nge-proboysis ye-sodium borohydride ye-acetic acid: i-NABH4 + 3 HO2CCH3 → i-nabh (O2cch3) 3 + 3 h2.

Ngenxa yemiphumo ye-steric kunye ne-elektroniki yamaqela e-Acetoxy, iSodium TriacetoXYBORORYCRYDRYDDDDDSTDDE inciphisa i-Arhente enciphisa i-sodhyride okanye i-sodium ye-cydanorohydride. Ngaphaya koko, uNabh (oac) 3 kuthintela iimveliso ezingenabuhlungu eziveliswe yi-sodium cyanoborohydride. Sodium triacetoxyborohydride is especially suitable for reductive aminations of aldehydes and ketones.
Nangona kunjalo, ngokungafaniyo noSodium cyanoboroDride, i-Triacetoxborohyborohydride ibuthathaka yamanzi, kwaye amanzi ayinakusetyenziswa njengesinyibilikisi kunye ne-reamenol. I-idilesi ihamba kancinci nge-ethanol kunye ne-isopropanol kwaye inokusetyenziswa kwezi. I-NABH (Oac) 3 inokusetyenziselwa ukunciphisa i-alkyting ye-amines yesibini ene-Aldehy-bisulfite Adducts.
