Cyclopentadienyl complexes synthesis

J. M. Birmingham, Adv. Organomet. Chem., 2,36S (1964). Excellent review of the first 10 years of transition-metal-cyclopentadienyl complex synthesis, including a tabular survey of known compounds to June, 1963. 

CyclopentadienylthaHium and its alkylated derivatives are used in the synthesis of metallocenes (qv) and other transition-metal cyclopentadienyl complexes (29).

Considerable effort has been directed to the stereoselective synthesis of aimulated cyclopentadienyl complexes of the group 4 transition metals. Ci asymmetric and C2 synunetric aimulated cyclopentadienyl ligands have been used to prepare chiral organotitanium complexes, which are now being actively studied as catalysts for asymmetric synthesis and olefin polymerization see Asymmetric Synthesis by Homogeneous Catalysis). 

The methylcyclopentadienylmolybdenum tricarbonyl synthesis illustrates how a cyclopentadienylpotassium solution can be prepared and then used to prepare a typical transition metal-cyclopentadienyl complex. By analogous procedures, one can prepare a wide variety of metal complexes of the anions of cyclopentadiene, indene, etc. The ferrocene and nickelocene syntheses illustrate how the procedure can be adapted to the...
