Ruthenium(III) Chloride uses:

Used as a pure reagent for spectroscopy. Used as a catalyst for the oxidative cyclization of 1,7-diene to oxepanediol. The tertiary carbon-hydrogen bond of the cyclic ether is hydroxylated with periodate or bromate.

Ruthenium(III) Chloride physical and chemical properties:

Ruthenium trichloride is a reddish-brown or black leaf-shaped crystal, which is easily deliquescent. The relative density is 3.11, decomposed into simple substance when it is higher than 500℃. It is insoluble in cold water and carbon disulfide, and decomposes in hot water, but hardly soluble in ethanol, but soluble in hydrochloric acid. It reacts with potassium iodide solution to form and precipitates iodide. When hydrogen sulfide is passed into the solution, it is precipitated as diruthenium trisulfide, which can form corresponding ammonia, cyanide, and nitroso groups with ammonia, potassium cyanide and potassium nitrite. The complex with sodium amalgam or titanium trichloride is reduced to blue divalent ruthenium ion.
