Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 wanda kuma aka sani da sodium triacetoxyhydroborate, wanda aka fi sani da STAB, wani sinadari ne mai sinadaran da ke dauke da dabarar Na(CH3COO)3BH. Kamar sauran borohydrides, ana amfani da shi azaman mai ragewa a cikin hadakar kwayoyin halitta. Ana shirya wannan gishirin mara launi ta hanyar protolysis na sodium borohydride tare da acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Duk da haka, ba kamar sodium cyanoborohydride ba, triacetoxyborohydride yana da sauƙin narkewar ruwa, kuma ba za a iya amfani da ruwa a matsayin mai narkewa tare da wannan reagent ba, kuma ba ya dace da methanol. Yana amsawa a hankali kawai da ethanol da isopropanol kuma ana iya amfani da shi tare da waɗannan. Haka kuma ana iya amfani da NaBH(OAc)3 don rage alkylation na amines na biyu tare da adducts na aldehyde-bisulfite.
Don Allah a tuntube mu don samun COA da MSDS. Na gode.
