The mechanism of the recently discovered, unusual tetrabutylammonium fluoride (TBAF) deacylation of cellulose esters has been investigated by methods including kinetic isotope …
Exploitation of desilylation chemistry in tailor-made ... - Nature
Mar 11, 2015 · The desilylation with tetra-n-butylammonium fluoride (TBAF) has proven to be very powerful in acetylene chemistry because of its simple synthetic procedure, high efficiency and …
TBAF-catalyzed deacylation of cellulose esters: Reaction scope …
Oct 15, 2013 · TBAF-catalyzed deacylation successful for wide variety of cellulose esters. Deacylation relatively insensitive to solvent type, water content. Deacylation surprisingly works …
An Operationally Simple and Efficient Work-up Procedure for TBAF ...
This method eliminates the tedious aqueous-phase extraction process to remove excess TBAF and materials derived from TBAF, thereby making the protocol highly amenable to multiple …
Experimental and Theoretical Studies on Stereomutation Through
Jan 2, 2024 · As an attempt at chemical conversions of the enantioenriched silyl-substituted gem -difluorocyclopropanes, we examined desilylation with tetrabutylammonium fluoride (TBAF). In …
p-fluorobenzaldehyde > benzaldehyde > p-anisaldehyde, and a possible mechanism is discussed. These experiments have preliminarily differentiated this cost-effective catalytic system from …
Glycan ester deacylation by TBAOH or TBAF: regioselectivity vs
Nov 26, 2014 · Tetrabutylammonium fluoride (TBAF) and tetrabutylammonium hydroxide (TBAOH) have been found to mediate regioselective deacylation of cellulose esters, with …
Exploitation of desilylation chemistry in tailor-made …
We present the concept for metal and HOPG surface modifications involving the formation of a metal–carbon (M–C) or C–C covalent bond via in situ desilylation of silyl-protected acetylene …
Tetra-n-butylammonium Fluoride (TBAF) - Common Organic …
TBAF is a quaternary salt that is used as a source of fluorine. The fluorine anion is typically used for deprotection of silyl ether groups or as a mild base. The good solubility of TBAF in organic …
