Electrochemically Driven Regioselective Radical Functionalization of Allenes: Scope and Mechanistic Insights

Advanced Science, EarlyView.
Allenes emerge as powerful platforms for electrochemical functionalization through radical pathways. Selective radical addition at the central carbon triggers anodic oxidation and intramolecular cyclization, enabling efficient synthesis of oxazolines and oxazolidine‐2‐imines without external oxidants.
