Enantioconvergent Deacylative Functionalization toward α‐Quaternary Nitriles

Angewandte Chemie, EarlyView.
An enantioconvergent quaternary‐to‐quaternary synthesis of α‐chiral nitriles has been enabled. By replacing the acyl group with a variety of allyl, propargyl, and benzyl motifs, the functional group swap can convert easily available β‐ketonitriles to assorted quaternary stereocenters en route to bioactive molecules of broad interests.

One‐step Oxidative Monofluorination of Electron‐Deficient Sulfoxides to Access Highly Lewis Acidic Sulfur(VI) Cations

Chemistry – A European Journal, Volume 28, Issue 69, December 9, 2022., 2022
Highly Lewis acidic fluorosulfoxonium cations can be prepared in a one‐step, chloride promoter‐free fashion from electron‐deficient sulfoxides using [FXe][OTf]. The latter is prepared by reaction of XeF2 with TMS‐OTf, thus representing an inversion of the previously described Umpolung strategy, which failed to convert the same sulfoxides efficiently ...

Molecularly Designed Cathode for Copper‐Benzimidazole‐Induced CO2 Reduction to MeOH

Angewandte Chemie, EarlyView.
A molecular cathode incorporating a strategically designed copper‐benzimidazole‐based electrocatalyst was developed for direct CO₂ capture and electrochemical conversion to methanol (e‐MeOH). This system follows a formato pathway, utilizing water as a proton source and thus eliminating the need for H₂ in e‐MeOH production.
