Half-sandwich compounds of zirconium(II): the synthesis of [Zr(η6-C7H8)(PMe3)2Cl2]
Abstract
Reduction of [ZrCI4] in the presence of cycloheptatriene and PMe3 forms [Zr(η6-C7H8)(PMe3)2Cl 2](1), and reaction of iodotrimethylsilane with [Zr(η7-C7H7)(PMe3)2](2), produced from [Zr(η6-C7H8)2](4)via[Zr(η7-C7H7)(tetrahydrofuran)2l](5), forms [Zr(exo-η6-C7H7SiMe3)(PMe3)2l2](3); the crystal structures of (1),(3),and (5) have been determined.
