  square-planar iridium(I) η2-cyclooctene complex, Ir(η2-C8H14)[N(SiMe2CH2PPh2)2], with excess 1,3-butadiene generates excellent yields of the five-coordinate iridium(I) 1,3-butadiene complex, Ir(C4H6)[N(SiMe2CH2PPh2)2]. Both the NMR spectral data and the single crystal X-ray structure reveal that the tridentate amido-diphosphine ligand is coordinated in a quasi facial manner and the 1,3-butadiene unit is bound

  The reactions of the coordinatively unsaturated iridium methylene complex IrCH 2 [N(SiMe 2 CH 2 PPh 2 ) 2 ] are described. This methylene complex is prepared by the reaction of 2 equiv of KOBu t with the methyl iodide derivative Ir(CH 3 )I[N(SiMe 2 CH 2 PPh 2 ) 2 ] in toluene; the extra equivalent of KOBu t serves to coordinate the HOBu t that is produced as the precipitate KOBu t -HOBu t .

• Synthesis and reactivity of the iridium vinylidene Ir:C:CH2[N(SiMe2CH2PPh2)2]. Formation of carbon-carbon bonds via migratory insertion of a vinylidene unit

  The synthesis of the 16-electron iridium vinylidene complex Ir=C=CH2[N(SiMe2CH2PPh2)2] is described by starting from the cyclooctene derivative Ir(eta-2-C8H14)[N(SiMe2CH2PPh2)2] with addition of acetylene. This vinylidene complex reacts with a variety of electrophiles; thus, reaction with AlR3 (R = Me, Et) or GaMe3 leads to the formation of the new derivatives Ir(ER2)CR=CH2[N(SiMe2CH2PPh2)2] (E = Al, R = Me, Et; E = Ga, R = Me). These complexes result from oxidative addition of the ER3 reagent to the coordinatively unsaturated Ir(I) vinylidene followed by migratory insertion to generate the carbon-carbon bond of the substituted vinyl moiety. Oxidative addition of methyl iodide generates as the final product the allyl iodide derivative Ir(eta-3-C3H5)I[N(SiMe2CH2PPh2)2]. This last transformation has been examined in detail using NMR spectroscopy to follow the course of the reaction. A number of intermediates could be observed: the first species is the oxidative adduct Ir=C=CH2(Me)I[N(SiMe2CH2PPh2)2], which undergoes migratory insertion to generate the isopropenyl iodide Ir(CMe=CH2)I[N(SiMe2CH2PPh2)2], which then rearranges to the allyl product. A third intermediate, believed to be an allene-amine derivative of the formula Ir(eta-2-H2C=C=CH2)I[HN(SiMe2CH2PPh2)2] ig observed but was found not to be on the pathway to the allyl complex. Extension to other alkyl halides was attempted; reactions with ethyl iodide and benzyl bromide do proceed, but the resultant product mixtures are complex.
