- base to
deprotonate the
carboxylic acid. The
conjugate base is the
carboxylate salt. In this case,
hydroxide is a
strong enough base to
deprotonate the carboxylic...
-
catalytic cycle the
auxiliary base (usually
triethylamine or pyridine)
deprotonates the
protonated DMAP,
reforming the catalyst. The
reaction runs through...
- form ketones. The
first equivalent of
nucleophile acts as a base and
deprotonates the acid. A
second equivalent will
attack the
carbonyl group to create...
- homopolymers, a
variety of
copolymers and
crosslinked polymers, and
partially deprotonated derivatives thereof, are
known and of
commercial value. In a
water solution...
- α-aminobenzylphenol. First, the lone-pair on the
nitrogen of the
imine deprotonates the phenol,
pushing the
bonding electrons onto the oxygen. The carbonyl...
- pure
water or in an
aqueous solution, in
which a
water molecule, H2O,
deprotonates (loses the
nucleus of one of its
hydrogen atoms) to
become a hydroxide...
-
susceptible to base-catalyzed hydrolysis. RNA
hydrolysis occurs when the
deprotonated 2’ OH of the ribose,
acting as a nucleophile,
attacks the
adjacent phosphorus...
-
thermodynamic product. A
weaker base such as an alkoxide,
which reversibly deprotonates the substrate,
affords the more
thermodynamically stable benzylic enolate...
-
extremely weak acid. Its pKa in DMSO is
estimated to be 56. It
cannot be
deprotonated in solution, but the

standard amino acid framework. At
physiological pH, the
carboxylic acid is
