Modern Physical Organic Chemistry
This trend reflects the relative basicities, as well. Below we will describe LFERs
for nucleophilicity and nucleofu- gality that correlate the pKas of the conjugate
acids of the nucleophiles and nucleofuges to sensitivity parameters (/Jnuc and /
JLc).

Chemistry of Protein Conjugation and Cross-Linking
Relationship between Nucleophilicity and Reactivity Most of the protein
modification reactions are nucleophilic reactions, involving a direct displacement
of a leaving group by the attacking nucleophile, which in this case is the amino
acid side ...

Advanced Organic Chemistry: Part A: Structure and Mechanisms
Nucleophilicity and Solvent Effects The term nucleophilicity refers to the effect of
a Lewis base on the rate of a nucleophilic substitution reaction and may be
contrasted with basicity, which is defined in terms of the position of an equilibrium
...

The Art of Writing Reasonable Organic Reaction Mechanisms
The nucleophilicity of a compound is measured by determining how reactive it is
toward CH3Br in water at 25 °C. Nucleophilicity bears some relationship toward
basicity, which measures reactivity toward H, but there are important differences.

Shriver and Atkins' Inorganic Chemistry
Key points: the nucleophilicity of an entering group is expressed in terms of the

Conceptual Problems In Organic Chemistry
nucleophilicity order decreases from left to right in non-H-bonding solvent like
acetone. (d) nucleophilicity order ... CH3,NH3,OH, F Among these nucleophiles,
which of the following orders is correct for their nucleophilicity order in gas phase
?

Chemistry of Protein and Nucleic Acid Cross-Linking and ...
Similarly, the greater the nucleophilicity of the attacking group, the more
expeditiously will the product be formed.15'16 In terms of protein modification, the
relative chemical reactivity is basically a function of the nucleophilicity of the
amino acid ...
Shan S. Wong, David M. Jameson, 2011

Electron Flow in Organic Chemistry: A Decision-Based Guide ...
electron-deficient carbon, so the relative hardness of the nonbonding electron
pair is important in any discussion of basicity versus nucleophilicity (see Section
9.5). To rank the nucleophilicity of a nonbonding electron pair, we must consider
...
