Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 inozivikanwawo se sodium triacetoxyhydroborate, inowanzo pfupikiswa STAB, ikemikari ine fomura Na(CH3COO)3BH. Kufanana nedzimwe borohydrides, inoshandiswa semushonga unodzikisa mukugadzirwa kweorganic. Munyu uyu usina ruvara unogadzirwa neprotolysis ye sodium borohydride ine acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.

Nekuda kwemhedzisiro ye steric uye electronic yemapoka eacetoxy, sodium triacetoxyborohydride inoderedza zvinyoro nyoro kupfuura sodium borohydride kana kunyange sodium cyanoborohydride. Uyezve, NaBH(OAc)3 inodzivirira zvigadzirwa zvine chepfu zvinogadzirwa ne sodium cyanoborohydride. Sodium triacetoxyborohydride inonyanya kukodzera kuderedza aldehydes nemaketones.
Zvisinei, kusiyana nesodium cyanoborohydride, triacetoxyborohydride haipindi mvura, uye mvura haigone kushandiswa semushonga une reagent iyi, uye haishande nemethanol. Inoshanda zvishoma nezvishoma ne ethanol ne isopropanol uye inogona kushandiswa neizvi. NaBH(OAc)3 inogonawo kushandiswa kuderedza alkylation ye secondary amines ne aldehyde-bisulfite adducts.
