Abstract

Cyclodimerization of two molecules of phenylacetylene at the ruthenium(II) centre in [(η-C5H5)Ru(η-C8H12= cyclo-octa-1,5-diene) gives the novel ruthenacyclopentatriene [(η-C4H5)Ru(C4Ph2H2)Br] characterized by 1H and 13C n.m.r. spectroscopy and by X-ray analysis; the triene undergoes facile ‘oxidative addition’ with donor ligands L (e.g. morpholine, trimethyl phosphite, dimethylphenylphosphine) in a bimolecular reaction involving an associative mode of activation to give the ruthenacyclopentadienes [(η-C5H5)Ru(L)(C4Ph2H2)Br].
