(η 4 -1,5-cyclooctadiene) (η 6 -1,3,5-cyclooctatriene) ruthenium is an organometallic ruthenium compound .
history
The first preparation of (η 4 -1,5-cyclooctadiene) (η 6 -1,3,5-cyclooctatriene) ruthenium, the first known ruthenium (0) -olefin complex, succeeded Ernst Otto Fischer in 1963. Fischer succeeded in the synthesis in low yield due to the reaction of ruthenium (III) chloride hydrate with 1,5-cyclooctadiene and 1,3,5-cyclooctatriene with reduction by a Grignard reagent . By choice of zinc for the reduction of the chloride the yield increases considerably.
Reactions
The complex is extremely reactive and the olefin ligands can easily be replaced by a number of other ligands such as phosphines , carbon monoxide or amines .
