Selective dehydrogenation of tetrahydroisoquinolines in the presence of sulfoxides
1,2,3,4-Tetrahydroisoquinolines undergo selective dehydrogenation in the presence of compounds with a highly polar X=O bond, particularly sulfoxides, under aerobic conditions to give the corresponding 3,4-dihydroisoquinolines. The reaction can be carried

Fundamental Understanding of Oxidative Stability in Fluorinated Asymmetric Ethers for Li Batteries
Angewandte Chemie, EarlyView.To improve Li‐metal battery electrolytes, we analyze fluorinated 1‐ethoxy‐2‐methoxyethane (FxEME) oxidative stability via density functional theory (DFT) and molecular dynamics (MD). Fluorination strengthens ethoxy C–H bonds and alters solvent orientation at the cathode, weakening interfacial interactions.
