Technology Process of Cyclopentadienylindenylzirconium dichloride

There total 3 articles about Cyclopentadienylindenylzirconium dichloride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 83.0%

lithium indenide (20669-47-0) + (η5-cyclopentadienyl)trichlorozirconium(dimethoxyethane) → (η5-cyclopentadienyl)(η5-indenyl) zirconium(IV) dichloride (80155-52-8)

Guidance literature:

In diethyl ether; toluene; Ar atmosphere; to suspn. of CpZrCl3DME in 3:1 toluene-diethyl ether at -78 °C diethyl ether soln. of LiC9H7 was added, stirred and allowed to warm to room temp. over 8 h; solvent removed under reduced pressure, residue extd. with CH2Cl2, suspn. cooled to -10 °C for 1 h, filtered, filtrate concd., pentane added, cooled to -18 °C for 12 h, filtered, filtrate concd., pentane added; elem. anal.;
