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. Packaging 100, 800 mL in Sure/Seal™
