Development of a High-Performance Thin-Layer Chromatography Method for the Quantification of Alkyl Glycerolipids and Alkenyl Glycerolipids from Shark and Chimera Oils and Tissues

Marine Drugs, 2022
Ether lipids are composed of alkyl lipids with an ether bond at the sn-1 position of a glycerol backbone and alkenyl lipids, which possess a vinyl ether bond at the sn-1 position of the glycerol.

Catalyst-controlled doubly enantioconvergent coupling of racemic alkyl nucleophiles and electrophiles

Science, 2020
Convergent coupling Metal-catalyzed coupling of two flat aromatic rings is one of the most versatile and widely applied chemical reactions. Efforts to extend this protocol to alkyl-alkyl coupling are complicated by the prospect of forming two different ...

Effect of Alkyl-group Flexibility on the Melting Point of Imidazolium-based Ionic Liquids [PDF]

J. Chem. Phys. 153, 044504 (2020), 2021
The low melting point of room temperature ionic liquids is usually explained in terms of the presence of bulky, low symmetry and flexible ions, with the first two factors related to the lattice energy while an entropic effect is attributed to the latter.
