Reactivity of co-ordinated ligands. Part XXVI. Some substitution reactions of tricarbonyl(η-cyclo-octa-1,5-diene)ruthenium

Abstract

Tricarbonyl(η-cyclo-octa-1,5-diene)ruthenium is a useful precursor in the preparation of a wide range of [(olefin)Ru(CO)₃] complexes. Thus reaction with olefin (olefin = cyclohexa-1,3-diene, cyclo-octatetraene, cyclo-octa-1,3,6-triene, cyclohepta-2,4,6-trien-1 -one, cyclohepta-1,3-diene, or cycloheptatriene) in benzene under reflux gives moderate to good yields of the appropriate [(olefin)Ru(CO)₃] complex.
