ʻO Tetrabutylammonium Fluoride Solution (TBAF) CAS 429-41-4 (75% i ka wai)

ʻO Tetrabutylammonium Fluoride (TBAF) (CAS: 429-41-4), he paʻakai fluoride a me ka paʻakai tetrabutylammonium.Loaʻa iā ia kahi hana ma ke ʻano he catalyst hoʻololi.
Catalyst no ka etherification o na waiona a me na phenols me na alkyl halides Ka mea nana no na hana benzylation.
ʻO ka TBAF kahi reagent i nā syntheses organik i hoʻohui ʻia, condensation, base-catalyzed cyclization reactions, fluorination a me desulfonylation reactions a ma ke ʻano he deprotecting agent.Hoʻomaloʻo maʻamau ma mua o ka hoʻohana ʻana.
Hoʻohana nui ʻia ʻo Tetrabutylammonium Fluoride i ke kahua o ka synthesis organik a hiki ke hoʻohana ʻia e like me ka fluorination reagent, silylation catalyst no nā alcohols, phase transfer catalyst, etc.
Hoʻohana ʻia ʻo Tetrabutylammonium Fluoride ma ke ʻano he fluorinating agent a me ka silylation catalyst no nā alcohols i ka synthesis organik, a ma ke ʻano he reagent maʻamau i ka alkylation a me nā hopena hydroxylation.ʻO ka catalyst hoʻoili pae cationic maikaʻi.Nā mea hoʻoheheʻe no ka acylation, silicification a me ka silicification
ʻO Tetrabutylammonium Fluoride kahi paʻakai fluoride hiki ke hoʻohana maʻamau.Hoʻohana ʻia ia ma ke ʻano he kumu, kahi hoʻololi hoʻololi ʻana, a me kahi kumu fluoride.Ma ke kahua noiʻi o ka hoʻomohala ʻana i ka sensor fluoride, hoʻohana ʻia ʻo TBAF ma ke ʻano he kumu maʻalahi e mālama a hiki ke ana.ʻO ka fluoride i loko o TBAF, i ka wā i hoʻoheheʻe ʻia, hiki ke noʻonoʻo ʻia he fluoride manuahi me ka liʻiliʻi o ka pilina me ka ammonium cation.No ka mea, ʻaʻole pono ʻo TBAF e komo i ka mālamalama ma nā lōʻihi nalu ʻoi aku ma mua o 240nm, pono ia e nānā i nā hopena ʻike me ka spectroscopy ʻike ʻia.
No ka mea, ʻo ka atom fluorine i loko o ka tetrabutylammonium fluoride he mea hoʻopaʻa paʻa hydrogen ikaika, he maʻalahi loa ke komo i ka makū, no laila ke kūʻai pinepine ʻia ka huahana Tetrabutylammonium fluoride trihydrate a i ʻole Tetrabutylammonium fluoride tetrahydrofuran solution.Ke hoʻomehana ʻia i ka 77 ℃ ma lalo o ka momi, e hoʻoheheʻe ka pūhui i ka paʻakai hydrogen fluoride.Ke hoʻomaloʻo ʻia ka hāpana ma 40 ℃ ma lalo o ka ʻūhā kiʻekiʻe, e loaʻa mau ana ka 10-30 mol% wai a me 10% difluoride paʻakai.
