Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 inozivikanwawo sesodium triacetoxyhydroborate, inowanzopfupikiswa STAB, ikemikari inosanganiswa ine fomula Na(CH3COO)3BH.Kufanana nedzimwe borohydrides, inoshandiswa sechinhu chinoderedza mu organic synthesis.Uyu munyu usina ruvara unogadzirwa neprotonolysis ye sodium borohydride ine acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.

Nekuda kweiyo steric uye yemagetsi mhedzisiro yemapoka eacetoxy, sodium triacetoxyborohydride inoderedza nyoro pane sodium borohydride kana kunyange sodium cyanoborohydride.Uyezve, NaBH(OAc)3 inodzivirira iyo ine muchetura parutivi-zvigadzirwa zvinogadzirwa nesodium cyanoborohydride.Sodium triacetoxyborohydride inonyanya kukodzera kune reductive aminations yealdehydes uye ketoni.

Zvisinei, kusiyana nesodium cyanoborohydride, triacetoxyborohydride inobata mvura, uye mvura haigoni kushandiswa sechinhu chinopisa neiyi reagent, uye haienderani nemethanol.Inoita zvishoma nezvishoma ne ethanol uye isopropanol uye inogona kushandiswa neizvi.NaBH(OAc)3 inogonawo kushandiswa kudzikisa alkylation yemamines echipiri ane aldehyde-bisulfite adducts.
