[ 1 ] - Hybrid-DFT study and NBO interpretations of the conformational behavior of 1,2-dihalodisilanes

Hybrid-density functional theory (B3LYP/Def2-TZVPP) based method and NBOinterpretation were used to investigate the conformational behavior of 1,2-dihalodisilanes[halo=F (1), Cl (2), Br (3), I (4)]. The B3LYP/Def2-TZVPP results showed that the anticonformations of compounds 1-4 are more stable than their corresponding gaucheconformations. The stability of the anti conformation compared to the g...

[ 2 ] - Hybrid-DFT study and NBO interpretations of conformational behaviors of 2-methoxy-1,2,4,5-tetrahydro-benzo[d]oxepine, -thiepine and -selenepine

NBO analysis and density functional theory (DFT: B3LYP/6-311+G**) based method were used to study the impacts of the anomeric effects (AE) on the conformational properties of 2-methoxy-1,2,4,5-tetrahydro-benzo[d]oxepine (1), -thiepine (2) and -selenepine (3). The Gibbs free energy difference (Geq–Gax) values (i.e. ΔGeq-ax) at 298.15 K and 1 atm between the axial and equatorial conformations inc...
