High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Redox Properties of Catalytically Generated Iminium Ions From α,β‐Unsaturated Aldehydes and Chiral Secondary Amines

European Journal of Organic Chemistry, EarlyView.
We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...
