Synthesis and reactions of hydrido(eta/sup 1/-allyl)- and hydrido(eta/sup 3/-allyl)iridium complexes
A system is reported in which isolable hydrido sigma- and ..pi..-allyl complexes can be prepared and their interconversions investigated. These complexes have often been postulated to be used as transient intermediates in organometallic reactions. Various iridium complexes were prepared, and the schemes for their preparation are discussed. In the eta/sup 3/-allyl hydride, the reactivity of allyl and hydride ligands leads to coordinated propane and provides an open coordination site for entry of both stabilizing and reactive ligands into the coordination sphere of the metal. The results presented here provide direct support for many alkene activation and isomerization mechanisms that have only been postulated in the past.
