Visible‐Light‐Mediated Regioselective Allylation, Benzylation, and Silylation of Methylene‐Malononitriles via Photoredox‐Induced Radical Cation Fragmentation
Visible‐light‐mediated regioselevtive allylation, benzylation, and silylation of methylene‐malononitriles with silanes have been realized. The reactions proceed via a photoredox‐catalyzed σ‐C–Si+· or σ‐Si–Si+· type radical cation fragmentation.
