13573-08-5 Usage
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
Different sources of media describe the Uses of 13573-08-5 differently. You can refer to the following data:
1. Reagent forms stable ionic adducts with carbenes.1
2. 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.
3. Reagent forms stable ionic adducts with carbenes.
Check Digit Verification of cas no
The CAS Registry Mumber 13573-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,7 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13573-08:
(7*1)+(6*3)+(5*5)+(4*7)+(3*3)+(2*0)+(1*8)=95
95 % 10 = 5
So 13573-08-5 is a valid CAS Registry Number.

Chemiluminescent reactions of ground and metastable states of the group IV a elements with halogens
Wang,Cheong,Parson
, p. 2834 - 2839 (2007/10/02)
Earlier work on chemiluminescent beam-gas reactions of the ground states (3Pj) of Si, Ge, and Sn with F2 and of both ground and metastable states (1D, 1S) of Sn with Cl 2, Br2, and I2 is extended to include reactions of both ground and metastable states of Si, Ge, and Sn with F2, Cl2, Br2, I2, and ICl. Chemiluminescent products of metal halides and/or dihalides were observed in all of these reactions, although attempts to observe that in the similar reactions of Pb were unsuccessful. In ICl reactions with Si, Ge, and Sn, both monochloride and dichloride emission occurs, confirming the previously proposed mechanism for creating dihalide emission in Sn reactions with Br2 and I2 via a monohalide intermediate.
