Like some other metallocenes, the C 5 H 5 ligands are displaceable. Thus, chromocene in combination with silica gel gives the Phillips catalyst for the polymerization of ethylene, although other preparations exist for this ...
Ernst Otto Fischer, who shared the 1973 Nobel Prize in Chemistry for work on sandwich compounds, first described the synthesis of chromocene. One simple method of preparation involves the reaction of chromium(II) chloride with sodium cyclopentadienide: CrCl2 + 2 NaC5H5 → Cr(C5H5)2 + 2 NaCl Such syntheses are typically conducted in tetrahydrofuran.
