Synthetic routes to an anionic zirconocene trihydride complex [Cp*2ZrH3]- 67 have been investigated. The original synthetic strategy involved the addition of KH or LiH to the zirconocene dihydride [Cp*2ZrH2] 10. Though this method proved to be reliable, generating the dihydride staring material was plagued by poor yields. An alternative synthetic route involved oxidative addition of dihydrogen to Zr(II) species generated in situ via the Negishi method. Again this allowed for the isolation of [Cp*2ZrH3]- 67 but it was contaminated with LiCl. A two-step process was eventually developed allowing for the facile high yielding synthesis of the first zirconocene trihydride anion 67. Initial reactivity studies of 67 were directed at exploring the nature of the hydride ligand. Analogies were drawn between the reactivity of 67 and the parent complex [Cp*2ZrH2] 10.
