A Comprehensive Study of the Solvent Effects on the Cycloaddition Reaction of Diethyl Azodicarboxylate and Ethyl Vinyl Ether: Efficient Implementation of QM and TD-DFT Study
In this work, quantum chemistry calculations performed to study the kinetics and thermodynamic parameters of [212]cycloaddition reaction of diethyl azodicarboxylate and ethyl vinyl ether in eighty-three solvents and gas ...
Implicit and explicit solvent effects on the selectivity of cycloaddition reaction of cyclopentadiene and methyl acrylate; a theoretical study
The product selectivity of the Diels–Alder reaction between cyclopentadiene and methyl acrylate has been studied through a solvent effect analysis by implicit and explicit solvent models. Two paths for this reaction have ...
Selective Binding of Cyclic Nanopeptide with Halides and Ion Pairs; a DFT-D3 Study
In this article, theoretical studies on the selective complexation of the halide ions (F-, Cl- and Br-) and ion pairs (Na+F-, Na+Cl- and Na+Br-) with the cyclic nano-hexapeptide (CP) composed of L-proline have been performed ...
Modeling of the Functionalized Gold Nanoparticle Aggregation in the Presence of Dopamine: A Joint MD/QM Study
The investigation of gold nanoparticle (AuNP) aggregation at the atomic level is a great challenge from the experimental view, while theoretical methods facilitate our understanding of the AuNP aggregation process. In this ...
Ortho-phenylenediamine Based Bis-ureas as the Ion Selective Sensors; A QM/MD Study
Density functional theory dispersion corrected (DFT-D3) calculations and molecular dynamic (MD) simulation were applied to investigate the sensing ability of four types of receptors (RCs) composed of the ortho-phenylenediamine ...
