Tetrabutylammonium Fluoride Solution (TBAF) CAS 429-41-4 (75% mu Madzi)

Tetrabutylammonium Fluoride (TBAF) (CAS: 429-41-4), ndi mchere wa fluoride ndi mchere wa tetrabutylammonium.Ili ndi gawo ngati chothandizira kutumiza magawo.
Chothandizira etherification wa mowa ndi phenols ndi alkyl halides Chothandizira benzylation zimachitikira.
TBAF ndi reagent mu organic syntheses kuphatikiza, condensation, base-catalyzed cyclization reactions, fluorination ndi desulfonylation reactions komanso ngati deprotecting agent.Childs zouma isanayambe ntchito.
Tetrabutylammonium Fluoride chimagwiritsidwa ntchito m'munda wa kaphatikizidwe organic ndipo angagwiritsidwe ntchito ngati reagent fluorination, silylation chothandizira kwa alcohols, gawo kutengerapo chothandizira, etc.
Tetrabutylammonium Fluoride ntchito monga fluorinating wothandizila ndi silylation chothandizira kwa alcohols mu kaphatikizidwe organic, ndi monga reagent zofunika mu alkylation ndi hydroxylation zimachitikira.Zabwino cationic gawo kutengerapo chothandizira.Zothandizira za acylation, silicification ndi sililicification
Tetrabutylammonium Fluoride ndi mchere wosungunuka wa fluoride womwe umagwiritsidwa ntchito kwambiri.Amagwiritsidwa ntchito ngati maziko, chothandizira chotengera gawo, komanso ngati gwero la fluoride.Pakafukufuku wa chitukuko cha sensa ya fluoride, TBAF imagwiritsidwa ntchito ngati gwero losavuta kunyamula komanso loyezeka la fluoride anion.Fluoride mu TBAF, ikasungunuka, ikhoza kuganiziridwa ngati fluoride yaulere yopanda kuyanjana pang'ono ndi ammonium cation.Popeza TBAF siyenera kuyamwa kuwala pamafunde okulirapo kuposa 240nm, ndikofunikira kuyang'anira momwe munthu akumvera ndi mawonekedwe owoneka bwino.
Popeza atomu fluorine mu tetrabutylammonium fluoride ndi wamphamvu haidrojeni chomangira chomangira, n'zosavuta kuyamwa chinyezi, choncho mankhwala kawirikawiri Tetrabutylammonium fluoride trihydrate kapena Tetrabutylammonium fluoride tetrahydrofuran njira amagulitsidwa.Ikatenthedwa mpaka 77 ℃ pansi pa vacuum, pawiriyo imawola kukhala mchere wa hydrogen fluoride.Zitsanzo zikaumitsidwa pa 40 ℃ pansi pa vacuum yayikulu, zimapezabe madzi 10-30 mol% ndi mchere wa difluoride 10%.
