Abstract We present a theoretical study of the [3+2] cycloaddition (32CA) reactions N‐benzyl fluoro nitrone with series maleimides producing isoxazolidines. use Molecular Electron Density Theory at MPWB1K/6‐311G(d) level. focus on reaction mechanism, selectivity, solvent, and temperature effects. In addition, we perform topological analyses minimal transition states to identify intermolecular interactions. Localization Function approach classifies as zwitterionic (zw‐) three‐atom components...

Abstract The inhibitory action of three dopamine derivatives on Fe (110) in 1 m HCl aqueous solution is studied by Density‐functional theory (DFT) calculations combined with Monte Carlo molecular dynamics (MD) simulations. It found that the predominant forms these compounds at acid pH adsorb spontaneously onto mild steel surface as charge transfer fraction values are positive, and aromatic rings approach parallel. computed adsorption energy exceed several hundred kcal mol −1 , thereby...

The [3+2] cycloaddition (32CA) reactions of N-methyl-C-(2-furyl) nitrone with maleimide derivatives have been studied in gas phase, ethanol and acetonitrile solvents within the Molecular Electron Density Theory (MEDT) framework at B3LYP-D3/6-31G(d) level. Topological analysis classifies as a zwitter-ionic (zw-) three atom component (TAC) associated high energy barrier, while global electron density transfer (GEDT) decreases requested cost for rupture olefinic double bond consequently...
