1
Carbanion chemistry: structures and mechanisms
This book describes their properties and structures, the conditions under which they form, and the factors that affect their thermodynamic and kinetic stability.
E. Buncel, Julian Michael Dust, 2003
2
Reactive Intermediate Chemistry
As you will see, the key element in these mechanisms is the ability to form a
carbanion that is reasonably stable, and often the kinetics of the reactions are
dominated by carbanion stability. The role of carbanion intermediates in
elimination ...

March's Advanced Organic Chemistry: Reactions, Mechanisms, ...
Formally, a carbanion is a trivalent carbon atom with an unshared electron pair,
and a formal charge of — 1. In fact, there are few carbanions that do not have an
anion-stabilizing group attached to the carbon atom. Stabilization may be by ...

Advanced Organic Chemistry: Part A: Structure and Mechanisms
... character of the carbon-lithium clusters. Since the electrons associated with the
carbanion are tightly associated with the cluster of lithium cations, some
activation energy is required to break the bond before the carbanion can act as a
base.
Francis A. Carey, Richard J. Sundberg, 2007
The carbanion exists in a trigonal pyramidal geometry. Formally a carbanion is the conjugate base of a carbon acid.
Jesse Russell, Ronald Cohn, 2012

on a monoprotic active site base after it has been abstracted to form the
carbanion intermediate. Exchange with this active site group was found to
correlate with the level of free reduced enzyme (112). Studies with the suicide
inhibitor ...

Enzyme-Catalyzed Electron and Radical Transfer
The fundamentals on which the carbanion mechanism is founded are the early
studies on the related enzymes D-amino acid oxidase (Walsh et al., 1972 and
1971), lactate oxidase (Walsh et al., 1973) and flavocytochrome b2 (Urban and ...

Process-Induced Food Toxicants: Occurrence, Formation, ...
An OH– ion abstracts an H+ from the RCH- of an amino acid [(RCH(NH2)COOH]
to form a negatively charged carbanion, which has lost its original asymmetry.
The carbanion can then recombine with a proton from the solvent to regenerate
the ...
