Technology Process of Dimethylsilylbis(tetramethylcyclopentadienyl)zirconium dichloride

There total 3 articles about Dimethylsilylbis(tetramethylcyclopentadienyl)zirconium 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: 82.0%

(C5(CH3)4)Si(CH3)2P(C6H11)(2-)*2Li(1+)=(C5(CH3)4Li)Si(CH3)2P(Li)(C6H11) + zirconium(IV) chloride (10026-11-6) → (C5(CH3)4)Si(CH3)2PC6H11ZrCl2 + {(dimethylsilanediyl)bis(2,3,4,5-tetramethyl-h(5)-cyclopentadienyl)}zirconium dichloride (100516-64-1)

Guidance literature:

In tetrahydrofuran; toluene; byproducts: (PCy)4; a soln. of Li2-salt in THF was added at -30 deg C under Ar to a suspn. of ZrCl4 in PhMe, mixt. was stirred at room temp. for 12 h; evapd. in vacuo, residue was washed with pentane, recrystd. from THF; X-ray anal., (1)H NMR spectral data;
