Displacement of the weakly ligated ethylene ligands in the complex Ru(CO)3{η2-C2H4}2 has been used to synthesise a series of tricarbonyl ruthenium compounds of η4-coordinated 1,3-dienes and 1,3-heterodienes. Complexes of η4-coordinated 1,3-heterodienes could not be isolated due to their extreme reactivity. Selected reactions were performed to replace a carbonyl at the metal centre with a phosphite, or to modify the coordinated ligand by standard methodologies. Single crystal X-ray analyses have been performed on the complexes [Ru(CO)3{(E,E)-1,4-diphenylbuta-1,3-diene}], [Ru(CO)3{ethyl(E,E)-5-phenylpenta-2,4-dien-1-oate}], [Ru(CO)3{(E,E)-5-phenylpenta-2,4-dienal}] and [Ru(CO)3{(E,E)-5-phenylpenta-2,4-dienol}] and indicate a change in electronic environment within the diene moiety on coordination.
