TRIS(CYCLOPENTADIENYL)YTTRIUM Usage And Synthesis

Uses

Tris(cyclopentadienyl)yttrium(III) is used as a pharmaceutical intermediate.

General Description

Atomic number of base material: 39 Yttrium

reaction suitability

core: yttrium
reagent type: catalyst

Synthesis

Tris(cyclopentadienyl)yttrium was prepared as follows: 0.6g of anhydrous yttrium trichloride was weighed and 0.53g of cyclopentadienyl sodium reacted in tetrahydrofuran, and the mixture was first evaporated to remove the solvent, and the remaining solid material was sublimated at 250??C under vacuum to obtain the pure metal cyclopentadienyl compound tris(cyclopentadienyl)yttrium.
