Intermediate isolated? The reaction of [Fe(CO) 5 ] with Me 2 NCCNMe 2 follows an unprecedented associative pathway to give the ferrabicyclobutenone 1 . Complexes such as 1 could be key intermediates in the iron‐mediated cyclization of alkynes to cyclopentadienones. Compound 1 undergoes a variety of CC coupling and CC‐bond‐cleavage reactions to afford a multitude of new organoiron compounds including 2 and 3 .
