N2 - The reaction of the dimer [Ir(μ-Cl)(coe)2]2 with two exocyclic dienes like N-substituted 4,5-dimethylene-2-oxazolidinones a and b, and KTpMe2 yields derivatives of the composition Tp Me2Ir(a or b) (1a,b). Derivative 1a reacts with Ph 2PC≡CPPh2, with the formal oxidative addition of the diene moiety to the metal center and coordination of the phosphine in the K1 mode. Derivatives 1a,b react with aromatic aldehydes to form the new compounds 3 (with benzaldehyde) and 4 (anisaldehyde), which contain an elaborated bidentate ligand formed by coupling of the two organic fragments (diene and aldehyde). The structures of compounds 3a,b have been determined by X-ray diffraction analysis.
