What is π-Olefin—iridium -komplexe : III. Über (η4-cyclodien)(η5-cyclodienyl)iridium-verbindungen, einen neuartigen hydridoiridium-komplex und das (η4-cyclooctadien)(η6-cyclooctatrien)iridium-kation about?

The complexes [Ir(COD)($-C,H,)] and [I~(COD)(TJ~-&H~ 1)] are obtained by the isopropyl Grignard synthesis of [tc(COD)Cl], (COD = ~4-1,5-cyclooctadiene) in the presence of cycloheptatriene and cyclooctatriene, respectively. The latter reaction yields [lrH(COD)(~4-1,3,6-CsH10)] as a by-product which, in contrast to other [IrH(q4-cyclodiene)J complexes, does not show H-addition:-elimination equilibria. Reduction of [Ir(l,3-C,H,,),Cl] with C,H,OH/Na,CO, yields CIr(r14-1,3-C7H10)(~S\_C7H9)] which was characterized by X-ray analysis. [Ir(COD)C1]2 reacts with Na,C,H,, end after hydrolysis unstable [Ir(COD)-($-C,H,)] is formed which by protonation with HPFs is converted into the [Ir(COD)(n"-l,3,5-C8HH,,)1' cation. All these compounds are fluxional in solution.
