Synthesis and Structure of the Smallest Cyclic Cumulene; Reaction of 1,3-Diynes with Zirconocene Complexes

The unexpected result of the reaction of “Cp2Zr” with di‐tert‐butadiyne was the formation of 1, the smallest possible cyclic cumulene. Other disubstituted butadiynes reacted with “Cp2M” by cleavage, dimerization, or dinuclear complex formation.
