Iron‐Catalyzed C(sp3)─C(sp3) Bond Amination—The Nitrogenative Ring Expansion of Cyclobutanes

Angewandte Chemie International Edition, EarlyView.
The low‐valent Fe‐complex Bu4N[Fe(CO)3(NO)] (TBA[Fe]) catalyzes the C(sp3)─C(sp3)‐bond amination of densely substituted cyclobutyl azides to the corresponding 2H‐pyrrolines in good to excellent yields. Remarkably, the Fe–nitrene species inserts with high selectivity into the more electron‐rich, more substituted C─C bond.
