13573-08-5
Synonyms
Germanium(II) diiodide
Application
Germanium(II) iodide serves multiple purposes in chemical applications, primarily as a versatile reagent involved in the formation of stable ionic adducts with carbenes. This yellow to gold flake or powder exhibits unique solubility properties; it can dissolve in cold water, concentrated hydriodic acid, and dilute acid, while displaying limited solubility in chloroform and carbon tetrachloride and remaining insoluble in carbon disulfide. Notably, it decomposes in hot water and reacts with ammonia solutions to form imine germanium, while sublimating at 240°C under vacuum. In synthetic chemistry, germanium(II) iodide is pivotal in the preparation of allylgermanes through its reaction with allylstannanes and facilitates the formation of homoallylic alcohols via its interaction with allyl bromide in the presence of zinc iodide followed by reactions with carbonyl compounds. Moreover, germanium(II) iodide is employed to achieve high yields of germanium nanocrystals, highlighting its role as an efficient catalyst in various reaction pathways. Its stability in dry air contrasts with its propensity to undergo hydrolysis in moist air, underscoring its reactivity and utility in diverse chemical environments.
