Description

Application

It can also be used in the synthesis of:

• Ruthenocene and fullerene molecular hybrid, Ru(η⁵- C₆₀Me₅)( η⁵-C₅H₅) (bucky ruthenocene).
• Allyl-substituted cyclopentadiene by palladium-catalyzed allylic alkylation.
• Bis(cyclopentadienyl)zirconium dichloride which is used as a catalyst in the synthesis of bis(indolyl)methanes and alkylation of heteroaryls.
• Cp-cobaltacycles from diphenylphosphinoalkynes and CoCl(PPh₃)₃.

Sodium cyclopentadienylide is a useful reagent for the preparation of metallocenes and cyclopentadienyl metal complexes.
