Chemical Ionization Mass Spectrometry, Second Edition
On the other hand, protonation of some organic bases by CI reagents such as
C4Hcj (protonated isobutene) or NH4 will be endothermic and. thus, rather slow.
In these cases, other reaction modes, such as clustering, may become important;
...

The Chemistry of Phenols, 2 Volume Set
ENERGETICS OF SOME FUNDAMENTAL PROCESSES A. Protonation
Protonation is a simple but important chemical process. The primary protonated
form is usually a pivotal intermediate that guides the subsequent steps of an
entire ...

Tetracyclines in Biology, Chemistry and Medicine
Upon deprotonation the acid yields the conjugate base, whereas protonation
converts the base into its conjugate acid. An orally administered drug will most
likely change its protonation state during its passage through the acidic stomach
and ...

Orotidine Monophosphate Decarboxylase: A Mechanistic Dialogue
4 Base Protonation Mechanisms Early proposals for the reaction mechanism of
ODCase favored mechanisms where the pyrimidine ring is protonated prior to
decarboxylation [5, 6]. Theoretical investigations have shown that a protonation
of ...

Recent Advances in Hydride Chemistry
Preferential protonation of the trans isomer illustrates the greater basicity of
hydrides that are trans to other hydrides. On cooling, a dihydrogen complex was
observed with a T,(min) of 35ms, slower than the relaxation rate of most
dihydrogen ...
M. Peruzzini, R. Poli, 2002

Biomedical Imaging: The Chemistry of Labels, Probes and ...
The individual stability constants are calculated from the log bpqr values with the
related protonation and equilibrium constants. The standard deviation values
calculated for the stability constants originate from random experimental error
and ...

Molecular Encapsulation: Organic Reactions in Constrained ...
In protonations and deprotonations there are two fundamentally different
pathways by which the proton can be transferred: the general and the specific
protonation. 48149 The terms general and specific have been coined for
acidcatalysis48 ...
