429-41-4 - Isicelo:

I-Tetrabutylammonium Fluoride (TBAF) (i-CAS: 429-41-4), ityuwa ye-fluoride kunye netyuwa ye-tetrabutylammonium.Inendima njenge-phase-transfer catalyst.
I-Catalyst ye-etherification ye-alcohols kunye ne-phenols ene-alkyl halides I-Catalyst ye-benzylation reactions.
I-TBAF yi-reagent kwi-organic syntheses ukongeza, i-condensation, i-base-catalyzed cyclization reactions, i-fluorination kunye ne-desulfonylation reactions kunye ne-arhente yokukhusela.Ngokuqhelekileyo yomiswe ngaphambi kokusetyenziswa.
I-Tetrabutylammonium Fluoride isetyenziswa ngokubanzi kwintsimi ye-organic synthesis kwaye ingasetyenziselwa njenge-reagent fluorination, i-silylation catalyst ye-alcohols, i-phase transfer catalyst, njl.
I-Tetrabutylammonium Fluoride isetyenziswa njenge-agent e-fluorinating kunye ne-silylation catalyst ye-alcohol kwi-organic synthesis, kunye ne-reagent esisiseko kwi-alkylation kunye ne-hydroxylation reactions.I-catalyst yokudluliselwa kwesigaba esihle se-cationic.Ii-Catalysts ze-acylation, i-silicification kunye ne-silicification
I-Tetrabutylammonium Fluoride yityuwa ye-soluble fluoride esetyenziswa rhoqo.Isetyenziswe njengesiseko, i-catalyst yokudlulisa isigaba, kunye nomthombo we-fluoride.Kwinkalo yophando yophuhliso lwesivamvo se-fluoride, i-TBAF isetyenziswa njengomthombo olula wokuphatha kunye nokulinganiswa kwe-anion ye-fluoride.I-fluoride kwi-TBAF, xa inyibilikisiwe, inokucingelwa njenge-fluoride yasimahla kunye nokunxibelelana okuncinci kunye ne-ammonium cation.Kuba i-TBAF kufuneka ingafunxa ukukhanya kubude bamaza angaphezu kwe-240nm, kuluncedo ukubeka esweni ukusabela kweemvakalelo nge-spectroscopy ebonakalayo.
Ekubeni i-athomu ye-fluorine kwi-tetrabutylammonium fluoride yinto eyomeleleyo ye-hydrogen bond yamkela, kulula kakhulu ukufunxa ukufuma, ngoko ke imveliso idla ngokuba yiTetrabutylammonium fluoride trihydrate okanye iTetrabutylammonium fluoride tetrahydrofuran isisombululo iyathengiswa.Xa ishushubezwa ukuya kutsho kwi-77℃ phantsi kwevacuum, ikhompawundi iya kubola ibe yityuwa yehydrogen fluoride.Xa isampulu yomisiwe kwi-40℃ phantsi kwevacuum ephezulu, isaza kufumana i-10-30 mol% yamanzi kunye ne-10% yetyuwa ye-difluoride.
