Ruthenium
What is Ruthenium?
Ruthenium is the chemical element with the atomic number 44, and is represented by the symbol Ru. Ruthenium is found associated with platinum ores. Ruthenium is a minor component in these ores and therefore is a relatively rare element. Ruthenium was discovered by Karl Karlovich Klaus, a Russian chemist, in 1844 while analyzing the residue of a sample of platinum ore obtained from the Ural Mountains. This central location bestows upon ruthenium properties that are common to both its early- and late-transition-metal cousins.
Ruthenium tends to occur along with deposits of platinum and is primarily obtained as a byproduct of mining and refining platinum. The special properties of ruthenium have opened up the area of olefin metathesis to synthetic organic and polymer chemists and are finally allowing this powerful reaction to realize its considerable promise. A literature search revealed that ruthenium chloride would polymerize related monomers in protic solvents.
