W (CO) 6 reaction

Tungsten hexachloride with pentacarbonyl iron role, generated hexacarbonyl tungsten. Fe (CO) □ carbon monoxide can occur with many ligand substitution reactions. Generation of mixed-ligand complexes of Fe (CO) L, □ □, where L is the PR □, □ AsR olefin or sulfur atom, etc. (R is alkyl). Yellow oily liquid; -21 ° C melting point, boiling point 102.8 ° C, the liquid density of 1.457 g / cm □ (21 ° C); 250 ° C decomposition of pure iron; insoluble in water, soluble in alkali, sulfuric acid, alcohol, benzene and petroleum ether . □ subjected to sunlight or ultraviolet irradiation of Fe (CO) dimerization to generate the Fe □ (CO) and carbon monoxide. Five carbonyl iron ether solution with mineral acid, decomposition into carbon monoxide, hydrogen, and ferrous iron. Strong base in aqueous or alcohol solution can be of Fe (CO) □ conversion into [HFe (CO) □] - anion
