Revised Method for Calculation of Group Electronegativities

Abstract

Since Wilmshurst’s method for calculation of group electronegativity has some defects, the revised method was proposed for counting the number of valence electrons (n*) on the central atom A in radical −AB, and group electronegativities of more than 150 substituents were reasonably calculated.

The effect of C-substituents on the topomerization mechanism, inversion barriers and electronic character of C N bond in N-alkylimines: A theoretical study

“…As opposed to authors of the work [15] we have not found the correlation of the DE i -values with C-substituents electronegativity (v) [27] (the electronegativity for CO 2 Me group and F were taken from references [28] and [29], respectively) and with the population of the nitrogen lone pair (N LP ) ( Table 2). …”

NMR study on the structure and stability of 4‐substituted aromatic iodosyl compounds

“…This is consistent with the distinct electron-withdrawing effect of the iodosyl group as expected from calculated group electronegativities. 17 Methanolic solution of 1-iodosyl-4-nitro-benzene has no long-term stability. After it was allowed to stand for several hours at room temperature, the 1 H NMR signals of 1-iodo-4-nitro-benzene appeared and increased steadily (Figs 1, 2).…”
