Cl prevents insertion : The first metallanaphthalyne 2 has been obtained by Zn reduction of Os carbyne complex 1 . The key to its isolation was the use of o ‐chlorophenyl instead of phenyl substituents to avoid formation of a putative hydrido metallanaphthalyne intermediate (supported by DFT calculations), which undergoes migratory insertion of the carbyne into the OsH bond and rearrangement to give an indenyl complex as the final product.
