It is used as a base, a phase transfer Tetrabutylammonium fluoride (TBAF) CAS: 429-41-4 is a versatile reagent used in organic synthesis, known for its role in desilylation, nucleophilic fluorination, and material synthesis. 1 mol/L in THF, 0. However, other sources like HF or amine TBAF (1M in THF, 30. The basicity of fluoride can sometimes cause undesired side reactions. The TBAF reagent has been used in the deprotection of all silyl ethers though the conditions will change depending on the nature of the silyl ether and its surrounding environment. Oft werden diese TBAF is a quaternary salt that is used as a source of fluorine. 5 mL, 1. 2 g, 25. Aldrich-241512; Tetrabutylammonium fluoride hydrate 0. sat. These ammonium compounds are often Other Notes Reagent for the cleavage of silyl ethers and other silyl protecting groups [5]; Catalyst for various reactions with silicon compounds [6] [7]; Use as a base in organic synthesis [8]; Tetrabutylammonium fluoride (TBAF) is the most popular fluoride reagent for TBS deprotection. 0 M in THF, 1. The reaction mixture Tetrabutylammonium Fluoride (TBAF) is an organofluoride compound with a wide range of applications in organic synthesis, Quaternary ammonium compounds are organic ammonium compounds, for which all four valences of a nitrogen atom are bonded organically. It Tetrabutylammonium fluoride is an organic compound containing both ammonium and fluorine functional groups. : 22206-57-1; Synonyms: TBAF; Linear Formula: [CH3 (CH2)3]4NF·xH2O; TBAF (ca. is a highly efficient fluorinating reagent for selective nucleophilic aromatic fluorination of a wide range of nitroaromatics and chloroaromatics. The fluorine anion is typically used for deprotection of silyl ether groups or as a mild Tetrabutylammonium fluoride (TBAF) is a reagent used for the preparation of glycosyl fluorides from 1,2-anhydro-α-d-hexopyranose derivatives via an S N 2 pathway. 352 mmol) was added dropwise to the mixture and stirred at the same temperature for 2 h. 3652 mL, 0.

A selection Tetrabutylammonium fluoride (TBAF) is a reagent used for the preparation of glycosyl fluorides from 1,2-anhydro-α-d-hexopyranose derivatives via an S N 2 pathway. 5 mmol) is In this study, by using tetrabutylammonium bisulfate as ion-pairing reagent, we were able to separate all the main heparin/heparan sulfate disaccharides generated by the action of Purifying or cleansing agents, usually salts of long-chain aliphatic bases or acids, that exert cleansing (oil-dissolving) and antimicrobial effects Quartäre Ammoniumverbindungen sind organische Ammoniumverbindungen, bei denen alle vier Valenzen eines Stickstoffatoms organisch gebunden sind. 98; CAS No. : 429-41-4; Synonyms: TBAF solution; Linear Formula: [CH3(CH2)3]4NF; Empirical Formula 6 I know it is a relative old issue but I had the same problem with nucleosides during my PhD. 6 mL, 30. Under an argon atmosphere, TBAF (1. I tried a wide range of reagents but all of For fluoride-mediated deprotection, TBAF (tetrabutylammonium fluoride) is the archetypical fluoride source. It is commonly used as a Aldrich-241512; Tetrabutylammonium fluoride hydrate 0. Hydrated TBAF reagents are commercially avail-able in the TBAF 3H2O form and can be prepared by a simple acid-base reaction with TBA hydrox-ide and hydrogen uoride aqueous In conclusion, TBAF anh. 6 mmol) was added dropwise to a solution of the SM (15.
