ChemInform Abstract: The Formation of Substituted Ferrocenes in the Reaction Between Iron Atoms, Cyclopentadiene, and Alkynes.

Abstract The example demonstrated in the scheme shows that cocondensation of iron atoms with cyclopentadiene and alkynes also incorporates the alkyne skeleton into a cyclopentadienyl ring leading to ferrocenes substituted on one of the cyclopentadienyl ring as well as the expected unsubstituted ferrocene.
