10250-52-9 Usage
General Description
Propylidene diiodide, also known as 1,3-diiodopropene, is a chemical compound with the formula C3H4I2. It is a pale yellow liquid at room temperature and is primarily used as a reagent in organic synthesis. Propylidene diiodide is commonly used in the preparation of pharmaceutical intermediates and agricultural chemicals. It is an important reagent for the synthesis of various types of organic compounds, including alkenes, alkynes, and aromatic compounds. Additionally, it is used as a precursor for the synthesis of functional materials and polymers. Propylidene diiodide is highly reactive and should be handled with extreme care due to its potential for causing skin and eye irritation, as well as being harmful if ingested or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 10250-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10250-52:
(7*1)+(6*0)+(5*2)+(4*5)+(3*0)+(2*5)+(1*2)=49
49 % 10 = 9
So 10250-52-9 is a valid CAS Registry Number.

Nucleophilic and electrophilic properties of diiodomethyl lithium and sodium
Charreau, P.,Julia, M.,Verpeaux, J. N.
, p. 275 - 282 (2007/10/02)
The previously unreported diiodomethylsodium has been prepared; its thermal stability as well as nucleophilc behaviour (alkylation leading to 1,1-diiodoalkanes and allylation leading either to 1,1-diiodo-3-alkenes or 1-iodoalkadiene) are described and compared with the corresponding reactions of the lithium carbenoid.Alternatively, both lithium and sodium derivatives of diiodomethane react as electrophiles with α-sulfonyl carbanions to give 1-iodoalkenes in good yield.
