Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

ABSTRACT Strained bicyclo[1.1.0]butanes (BCBs) have emerged as versatile precursors for accessing highly reactive intermediates, enabling unconventional bond constructions through strain‐release pathways. Herein, we report a cobalt(II)‐catalyzed strategy that combines thermal act...
