Titanocene dichloride CAS# 1271-19-8

Magnesium powder, anthracene, and tetrahydrofuran solution were added under the protection of nitrogen and a few drops of iodomethane were added. , stirring at a certain temperature to obtain a yellow-green liquid. At the end of the process, it was placed in an ultrasonic shaker for 4h to obtain an activated orange-yellow precipitate of anthracene magnesium. The solution of cyclopentadiene Chemicalbook and titanium tetrachloride was added dropwise at 60°C for 20 min and then cooled to room temperature, filtered, and the filtrate was washed with dichloromethane. The washed filtrate was combined with the filtrate and concentrated to an appropriate amount and crystallized under an ice bath. Red dicyclopentadiene titanium dichloride crystals were obtained. The yield of this method was reported to be about 65% in the literature. It is an efficient hydrogenation catalyst, mainly used in olefin polymerization and hydrogenation reaction, and it can be used as an efficient and low toxic active substance in medicine. It is used in the hydrogenation of butylbenzene block copolymers and also used in the synthesis of α-γ-butyrolactone from benzaldehyde and bromomethacrylic acid. Titanocene dichloride is an efficient homogeneous reaction catalyst for olefin polymerization and hydrogenation reaction; used in the synthesis of α-methylene-γ-butyrolactone by one-pot method with benzaldehyde and bromomethyl acrylate.
