Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 kuma aka sani da sodium triacetoxyhydroborate, wanda aka fi sani da STAB, wani sinadari ne mai hade da dabara Na (CH3COO) 3BH.Kamar sauran borohydrides, ana amfani dashi azaman wakili mai ragewa a cikin ƙwayoyin halitta.Ana shirya wannan gishiri mara launi ta hanyar protonolysis 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 ruwa, kuma ba za a iya amfani da ruwa azaman sauran ƙarfi tare da wannan reagent ba, kuma bai dace da methanol ba.Yana amsawa kawai a hankali tare da ethanol da isopropanol kuma ana iya amfani dashi tare da waɗannan.Hakanan za'a iya amfani da NaBH(OAc)3 don rage alkylation na amines na biyu tare da adducts aldehyde-bisulfite.
Pls tuntube mu don samun COA da MSDS.Godiya.
