The reaction of the dimer [Ir(![]()
SRC="/images/entities/mgr.gif">-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 TpMe2Ir(a or b) (1a,b).Derivative 1a reacts with Ph2PC
s/entities/tbd1.gif">CPPh2, with the formal oxidative addition of the diene moiety to themetal center and coordination of the phosphine in the s/gifchars/kappa.gif" BORDER=0 >1 mode. Derivatives 1a,b react with aromaticaldehydes to form the new compounds 3 (with benzaldehyde) and 4 (anisaldehyde), which contain anelaborated bidentate ligand formed by coupling of the two organic fragments (diene and aldehyde). Thestructures of compounds 3a,b have been determined by X-ray diffraction analysis.
