Numerous studies on nitro group properties are associated with its high electron-
withdrawing ability, by means of both resonance and inductive effect. The substituent effect …

Aromaticity/aromatic and substituent/substituent effects belong to the most commonly used
terms in organic chemistry and related fields. The quantitative description of aromaticity is …

Effects of electron-donating (R= NH2) and electron-withdrawing (R= NO2) groups on 13C
NMR chemical shifts in R-substituted benzene are investigated by molecular orbital …

Nitro-substituted heteroaromatic carboxamides 1a-e were synthesized and tested against
three Mycobacterium tuberculosis cell lines. The activities can be explained in terms of the …

Electron-accepting properties of the nitro group were studied in a series of meta-and para-X-
substituted nitrobenzene derivatives (X= NMe 2, NH 2, OH, OMe, CH 3, H, F, Cl, CF 3, CN …

Two short novel series of five membered heterocyclic 3, 5-disubstituted–Isoxazole ether-
linked Isoxazoline derivatives (Xa–f) and 3, 5-disubstituted-Pyrazole ether-linked …

Most often, the substituent effects are described using rather troublesome Hammett
constants. Quite recently, it has been proposed to use the so‐called substituent energy …

Nitrogen-rich heterocyclic energetic compounds (NRHECs) and their salts have witnessed
widespread synthesis in recent years. The substantial energy-density content within these …

Proximity effects occur between vicinal functional groups or between a group and a specific
molecular fragment in close proximity, for example an endocyclic N atom in the ortho …

An application of quantum chemical modeling allowed us to investigate a substituent effect
on a σ and π electron structure of a ring and the nitro group in a series of meta-and para-X …
