Computational Calculation of Nitrobenzene and Its Derivatives

open access: yesIndonesian Journal of Chemical Research, 2022
Nitrobenzene is one of benzene derivatives. Nitrobenzene can be found naturally and also from the synthesis process. Nitrobenzene is used as a raw material to synthesize aniline, textile dyes, pesticides, and drugs. Nitrobenzene is a solvent in the paint

1-(2,5-Dimethoxy-4-nitrophenyl)piperidine

open access: yesMolbank, 2023
Treatment of the non-purified mixture of dinitro isomers obtained from the nitration of 1,4-dimethoxybenzene with piperidine led to the isolation of novel but minor adduct, 1-(2,5-dimethoxy-4-nitrophenyl)piperidine (2b) in 15% yield.

Probing the mechanism of electron capture and electron transfer dissociation using tags with variable electron affinity [PDF]

open access: yes, 2009
Electron capture dissociation (ECD) and electron transfer dissociation (ETD) of doubly protonated electron affinity (EA)-tuned peptides were studied to further illuminate the mechanism of these processes. The model peptide FQpSEEQQQTEDELQDK, containing a

Synthesis, kinetics and mechanism of nucleophilic substitution in octahedral (cat)2Sn(py)2 [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
Dicatecholatodipyridinetin(IV) in nitrobenzene showed an increase in molar conductance with time, suggesting solvation of the complex. In the presence of nucleophilic reagents, such as SOCl2, C6H5COCl and CH3COCl, the conductance increased sharply owing ...
