Modular Access to α‐Tertiary Amines: Electrochemical Tandem Di‐Functionalization of Olefins With Ammonia Surrogates and Amino Acids

Angewandte Chemie, EarlyView.
A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

Two‐Dimensional Quaternary Alloys of (RuMoVNb)Se2 for Superior Hydrogen Evolution Reaction Catalysis

Advanced Science, EarlyView.
Composition‐tuned (RuMoVNb)Se2 quaternary alloy nanosheets are synthesized via colloidal reactions. Incorporation of Ru into (MoVNb)Se2 ternary alloys results in more metallic electronic structures and significantly enhances their electrocatalytic activity for the hydrogen evolution reaction (HER) under alkaline, acidic, and neutral conditions.
