3synthesis methods
Preparative Methods of BIS(CYCLOPENTADIENYL)ZIRCONIUM DIHYDRIDE: the following method is convenient for the preparation of Cp2ZrH2. μ-Oxobis[chlorobis(η5- cyclopentadienyl)zirconium] ([Cp2ZrCl]2O) is prepared by the reaction of Dichlorobis(cyclopentadienyl)zirconium (Cp2ZrCl2), available from commercial sources, in dichloromethane and water in aniline. To a solution of [Cp2ZrCl]2O in THF is added dropwise Lithium Aluminum Hydride in THF with stirring under an argon atmosphere. The reaction mixture is stirred for ca. 8 h at rt, filtered, and then washed with THF to give the Cp2ZrH2 complex as a white solid (eq 1)[1].
