The synthesis and reactivity of some hydrocarbyl complexes of iron and ruthenium
We have reviewed the synthesis and properties of ethylene-bridged dinuclear transition metal complexes. The ethylene-bridged ruthenium complex [CpRu(CO)₂]₂[μ-(CH₂CH₂)] has been prepared. The characterization data (IR, ¹H and ¹³C NMR, and Mass spectral) and properties of this complex are discussed. T...
