Bis(pentamethylcyclopentadienyl)zirconium dichloride

Description:

Bis(pentamethylcyclopentadienyl)zirconium dichloride, with the CAS number 54039-38-2, is a transition metal complex featuring zirconium as the central metal atom. This compound is characterized by its two pentamethylcyclopentadienyl (Cp*) ligands, which are bulky and electron-rich, providing significant steric and electronic effects. The dichloride component indicates the presence of two chloride ions coordinated to the zirconium center. This complex is typically used in organometallic chemistry and catalysis, particularly in olefin polymerization processes due to its ability to activate and stabilize reactive intermediates. The steric bulk of the Cp* ligands enhances the stability of the complex and influences its reactivity. Additionally, the compound is often characterized by its solubility in organic solvents, making it suitable for various synthetic applications. Its unique structure and properties make it a valuable precursor in the development of advanced materials and in the study of metal-ligand interactions.

Bis(pentamethylcyclopentadienyl)zirconium dichloride

CAS: 54039-38-2

Bis(pentamethylcyclopentadienyl)zirconium dichloride (BPCZrCl2) is a zirconium-based metallocene. It is used as a catalyst in the production of polymers, such as polyethylene and polypropylene, which are used to produce plastics. BPCZrCl2 has been shown to be capable of producing cyclopentadiene and methylcyclopentadiene as reaction products. These compounds have been found to be labile, so they can be easily removed from the polymerization process. BPCZrCl2 is also a cocatalyst with high reactivity and stability. This property allows it to be used in reactions that involve multiple nuclear species, such as the termination of olefinic chains by metallocenes.
