75181-08-7 - Introduction
Pentamethylcyclopentadienylhafnium(IV) trichloride is an organometallic compound having the formula C10H15Cl3Hf. It is a colorless solid, stable at room temperature. Its melting point is about 135-137 degrees Celsius.
Pentamethylcyclopentadienylhafnium(IV) trichloride are widely used in the field of catalysts and metal organic chemistry. It is often used in the synthesis of catalysts, especially for the polymerization of olefins and the transfer hydrogenation of olefins. It can also be used in organic synthesis reactions, such as the addition of olefins, the epoxidation of olefins and asymmetric synthesis.
The method for preparing Pentamethylcyclopentadienylhafnium(IV) trichloride is generally obtained by reacting pentamethylcyclopentadienyl lithium with hafnium(IV) trichloride. The specific procedure is to dissolve lithium pentamethylcyclopentadienyl in diethyl ether and then react with hafnium (IV) trichloride to produce the desired product. After completion of the reaction, the Pentamethylcyclopentadienylhafnium(IV) trichloride can be obtained by filtration or concentration.
When using Pentamethylcyclopentadienylhafnium(IV) trichloride, it should be noted that it is an organic hafnium compound, which has certain toxicity and irritation. Good laboratory practice should be followed during operation and personal protective equipment should be used. At the same time, its solution and steam are also harmful, and should avoid inhalation or contact with skin and eyes.
