Relationship between basicity and nucleophilicity
(2007)
The empirical concepts of basicity and nucleophilicity are related but not strictly proportional. Hence, the aim of this study is to help in elucidating the range where both concepts are directly proportional. To do this, ...
A further exploration of a nucleophilicity index based on the gas-phase ionization potentials
(ELSEVIER SCIENCE BV, 2008)
An empirical nucleophilicity index based on the gas-phase ionization potentials has been recently shown to be useful categorizing and settling the nucleophilicity power of a series of captodative ethylenes reacting in ...
Nucleophilicity scale for n- and pi-nucleophiles
(ELSEVIER, 2006-08-31)
A recently introduced empirical nucleophilicity index for a series of n- and pi-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
Nucleophilicity scale for n- and π-nucleophiles
(2006)
A recently introduced empirical nucleophilicity index for a series of n- and π-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
Definition of a nucleophilicity scale
(AMER CHEMICAL SOC, 2006-07-06)
This work deals with exploring some empirical scales of nucleophilicity. We have started evaluating the experimental indices of nucleophilicity proposed by Legon and Millen on the basis of the measure of the force constants ...
Nucleophilicity index from perturbed electrostatic potentials
(2007)
We introduce and test a nucleophilicity index as a new descriptor of chemical reactivity. The index is derived from a perturbation model for the interaction between the nucleophile and a positive test charge. The computational ...
Are Electrophilicity and Electrofugality Related Concepts? A Density Functional Theory Study
(2011)
It is proposed that the electrofugality of a fragment within a molecule is determined by its group nucleophilicity. The variation of electrofugality should be tightly related to the electron releasing ability of the ...
Are Electrophilicity and Electrofugality Related Concepts? A Density Functional Theory Study
(2011)
It is proposed that the electrofugality of a fragment within a molecule is determined by its group nucleophilicity. The variation of electrofugality should be tightly related to the electron releasing ability of the ...
New dual descriptor for chemical reactivity
(AMER CHEMICAL SOC, 2005)
In this paper, a new dual descriptor for nucleophilicity and electrophilicity is introduced. The new index is defined in terms of the variation of hardness with respect to the external potential. and it is written as the ...
Mono- and Bis-alkylated lumazine sensitizers: Synthetic, molecular orbital theory, nucleophilic index and photochemical studies
(Wiley Blackwell Publishing, Inc, 2021-01)
Mono- and bis-decylated lumazines have been synthesized and characterized. Namely, mono-decyl chain [1-decylpteridine-2,4(1,3H)-dione] 6a and bis-decyl chain [1,3-didecylpteridine-2,4(1,3H)-dione] 7a conjugates were ...
