ʻO Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 i ʻike ʻia hoʻi ʻo sodium triacetoxyhydroborate, i hoʻopōkole pinepine ʻia ʻo STAB, he hui kemika me ke ʻano Na(CH3COO)3BH. E like me nā borohydrides ʻē aʻe, hoʻohana ʻia ia ma ke ʻano he mea hoʻemi i ka synthesis organik. Hoʻomākaukau ʻia kēia paʻakai kala ʻole e ka protonolysis o ka sodium borohydride me ka waikawa acetic: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Eia nō naʻe, ʻaʻole e like me ka sodium cyanoborohydride, he mea maʻalahi ka triacetoxyborohydride i ka wai, a ʻaʻole hiki ke hoʻohana ʻia ka wai ma ke ʻano he mea hoʻoheheʻe me kēia reagent, ʻaʻole hoʻi e kūlike me ka methanol. Hoʻopili mālie wale ia me ka ethanol a me ka isopropanol a hiki ke hoʻohana ʻia me kēia mau mea. Hiki ke hoʻohana ʻia ʻo NaBH(OAc)3 no ka alkylation reductive o nā amines lua me nā aldehyde-bisulfite adducts.
E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e kiʻi i ka COA a me ka MSDS. Mahalo.
