• Description: Germanium diiodide (also named as germanium (II) iodide) is a yellow crystalline solid which decomposes on melting. Its specific density is 5.37. It can be sublimed at 240°C in a vacuum.1 It can be used to obtain high yield of germanium nanocrystals.2
• Uses: Reagent forms stable ionic adducts with carbenes.1 Germanium(II) iodide acts as a reagent that forms stable ionic adducts with carbenes. It is also used in the preparation of allylgermanes by reacting with allylstannanes. Further, it reacts with allyl bromide in the presence of zinc iodide to get allylgermanium(IV), which on reacts with carbonyl compounds to give the corresponding homoallylic alcohols. Reagent forms stable ionic adducts with carbenes.
