Electrochemical Ring‐Opening 1,3‐Diamination of Arylcyclopropanes With Dibenzenesulfonimide and Nitriles

ABSTRACT We disclose a novel electrochemical approach for the 1,3‐diamination of arylcyclopropanes employing sulfonimide and nitriles as nitrogen sources. This environmentally benign and operationally simple protocol utilizes inexpensive and readily available dibenzenesulfonimide, eliminating the need for stoichiometric external redox reagents. Conducted under constant‐current electrolysis, the method enables efficient ring‐opening functionalization of a wide range of arylcyclopropanes, delivering structurally diverse 1,3‐diamine derivatives in moderate to excellent yields.
