429-41-4 - Daim Ntawv Thov:

Tetrabutylammonium Fluoride (TBAF) (CAS: 429-41-4), yog fluoride ntsev thiab tetrabutylammonium ntsev.Nws muaj lub luag haujlwm raws li theem-hloov catalyst.
Catalyst rau etherification ntawm cawv thiab phenols nrog alkyl halides Catalyst rau benzylation tshuaj.
TBAF yog ib qho reagent nyob rau hauv cov organic syntheses ntxiv, condensation, base-catalyzed cyclization cov tshuaj tiv thaiv, fluorination thiab desulfonylation cov tshuaj tiv thaiv thiab raws li ib tug deprotecting neeg sawv cev.Feem ntau qhuav ua ntej siv.
Tetrabutylammonium Fluoride yog dav siv nyob rau hauv lub teb ntawm organic synthesis thiab yuav siv tau raws li fluorination reagent, silylation catalyst rau cawv, theem hloov catalyst, thiab lwm yam.
Tetrabutylammonium Fluoride yog siv los ua tus neeg sawv cev fluorinating thiab silylation catalyst rau cawv hauv cov organic synthesis, thiab ua ib qho reagent hauv alkylation thiab hydroxylation.Zoo cationic theem hloov catalyst.Catalysts rau acylation, silicification thiab silicification
Tetrabutylammonium Fluoride yog ib qho uas nquag siv organic soluble fluoride ntsev.Nws yog siv los ua lub hauv paus, theem hloov pauv catalyst, thiab ua cov tshuaj fluoride.Hauv kev tshawb fawb txog kev txhim kho fluoride sensor, TBAF yog siv los ua ib qho yooj yim los lis thiab ntsuas tau fluoride anion qhov chaw.Cov tshuaj fluoride hauv TBAF, ib zaug yaj, tuaj yeem xav tias yog cov tshuaj fluoride dawb nrog kev sib cuam tshuam me ntsis nrog ammonium cation.Txij li thaum TBAF yuav tsum tsis txhob nqus lub teeb ntawm lub wavelengths ntau dua 240nm, nws yog ib qho tseem ceeb los saib xyuas cov kev xav ntawm cov spectroscopy pom.
Txij li thaum cov fluorine atom nyob rau hauv tetrabutylammonium fluoride yog ib tug muaj zog hydrogen daim ntawv cog lus txais, nws yog heev yooj yim mus nqus dej noo, yog li cov khoom feem ntau yog Tetrabutylammonium fluoride trihydrate los yog Tetrabutylammonium fluoride tetrahydrofuran kua.Thaum nws yog rhuab mus rau 77 ℃ nyob rau hauv lub tshuab nqus tsev, lub compound yuav decompose rau hydrogen fluoride ntsev.Thaum cov qauv qhuav ntawm 40 ℃ hauv qab lub tshuab nqus tsev siab, nws tseem yuav tau txais 10-30 mol% dej cov ntsiab lus thiab 10% difluoride ntsev.
