Ab Initio Molecular Dynamics Study of Aqueous Solvation of Ethanol and Ethylene [PDF]

, 2002
The structure and dynamics of aqueous solvation of ethanol and ethylene are studied by DFT-based Car-Parrinello molecular dynamics. We did not find an enhancement of the structure of the hydrogen bonded network of hydrating water molecules.

Facile preparation of efficient Cu-SiO2 catalysts using a polyhydroxy molecular template to regulate surface copper species for dimethyl oxalate hydrogenation

Catalysis Communications, 2023
β-cyclodextrin (β-CD) was used to prepare remarkable and stable copper-based catalysts for hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The DMO conversion (95.6% vs. 99.9%), EG selectivity (53.6% vs. 97.4%) and lifetime (25 h vs.

Access to enantioenriched compounds bearing challenging tetrasubstituted stereocenters via kinetic resolution of auxiliary adjacent alcohols

Nature Communications, 2021
A large number of enantiopure substances, such as those with tetrasubstituted carbon centres bearing several similar substituents, are inaccessible due to the incapability of chiral catalysts/ligands to recognize those substrates.
