ʻO ka sodium triacetoxyborohydride (STAB) CAS 56553-60-7 i ʻike pū ʻia ʻo sodium triacetoxyhydroborate, i hoʻopaʻa pinepine ʻia ʻo STAB, he mea hoʻohui kemika me ke ʻano Na(CH3COO)3BH.E like me nā borohydride ʻē aʻe, hoʻohana ʻia ia ma ke ʻano he mea hōʻemi i ka synthesis organik.Hoʻomākaukau ʻia kēia paʻakai kala ʻole e ka protonolysis o ka sodium borohydride me ka acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Eia naʻe, ʻaʻole e like me ka sodium cyanoborohydride, ʻo ka triacetoxyborohydride he mea maʻalahi ka wai, a ʻaʻole hiki ke hoʻohana ʻia ka wai ma ke ʻano he mea hoʻoheheʻe me kēia reagent, ʻaʻole hoʻi i kūpono me ka methanol.Hiki ke hana mālie me ka ethanol a me ka isopropanol a hiki ke hoʻohana pū me kēia.Hiki ke hoʻohana ʻia ka NaBH(OAc)3 no ka hoʻohaʻahaʻa alkylation o nā amine lua me nā mea hoʻohui aldehyde-bisulfite.
Pls e kelepona mai iā mākou e kiʻi iā COA a me MSDS.Mahalo.
