Bis(pentamethylcyclopentadienyl)hafnium dichloride

Description:

Bis(pentamethylcyclopentadienyl)hafnium dichloride, commonly referred to as bis(pentamethylcyclopentadienyl)hafnium(IV) dichloride, is a coordination compound featuring hafnium in a +4 oxidation state. This compound is characterized by its two pentamethylcyclopentadienyl (Cp*) ligands, which are bulky and electron-rich, providing significant steric and electronic effects. The presence of two chloride ions contributes to its dichloride designation. Typically, this compound appears as a solid and is soluble in organic solvents, making it useful in various applications, particularly in organometallic chemistry and materials science. Its structure allows for the formation of hafnium-based thin films, which are valuable in semiconductor manufacturing. The compound is also of interest in catalysis and as a precursor for hafnium oxide in high-k dielectric materials. Safety precautions should be observed when handling this compound, as it may pose health risks due to its chemical reactivity and potential toxicity.

Controlled Product

CAS: 85959-83-7

Bis(pentamethylcyclopentadienyl)hafniumdichloride (BPMC-HfCl2) is an enantioselective catalyst that is used in organic synthesis. The catalyst converts unsaturated alkyl groups, halogen compounds and quinoline derivatives to their corresponding β-amino acid analogs. BPMC-HfCl2 can also be used to synthesize glycol ethers from ethyl alcohol and ethylene glycol. The catalyst has been shown to be stable in the presence of a cationic surfactant and β-amino acid, which are common substrates for the reaction.
