There total 4 articles about diphenyl dicyclopentadienyl-zirconium 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: 95.0%

zirconocene dichloride (1291-32-3) + phenylmagnesium bromide (100-58-3) → diphenyl dicyclopentadienyl-zirconium (51177-89-0)

Guidance literature:

In 1,4-dioxane; diethyl ether; at 21°C; a side-arm flask equipped with a stir bar charged with (C5H5)2ZrCl2 and diethyl ether, added a soln. ((C2H5)2O) of C6H5MgBr (2.5equiv.) with stirring, stirred for 10 min, added dioxane, stirred for 1 5 h; volatiles removed under reduced pressure, solid extd. with toluene, filtered through Celite-padded coarse frit, filtrate collected, toluene removed under reduced pressure;
