1793-91-5 Usage
General Description
Tetraallylgermane is a chemical compound with the molecular formula C12H20Ge. It is a colorless to pale yellow liquid that is insoluble in water, but soluble in organic solvents. Tetraallylgermane is primarily used as a precursor in the synthesis of other organogermanium compounds, which have applications in the production of semiconductors, polymerization catalysts, and as pharmaceutical intermediates. It is also used in the formulation of coatings, adhesives, and sealants. Tetraallylgermane is known to be toxic if ingested or inhaled, and may cause irritation to the skin and eyes upon contact. Therefore, it should be handled and used with caution in a well-ventilated area and with proper personal protective equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 1793-91-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1793-91:
(6*1)+(5*7)+(4*9)+(3*3)+(2*9)+(1*1)=105
105 % 10 = 5
So 1793-91-5 is a valid CAS Registry Number.

Reactivity of dianionic hexacoordinate germanium complexes toward organometallic reagents. A new route to organogermanes
Cerveau,Chuit,Corriu,Reyé
, p. 1510 - 1515 (2008/10/08)
Lithium and potassium tris(benzene-1,2-diolato)germanates (2a and 2b, respectively) and potassium tris(butane-2,3-diolato)germanate (3) are easily prepared from GeO2 in quantitative yields. They are very reactive toward organometallic reagents, the reactivity depending on the ligands on the germanium. Complexes 2 react with an excess of Grignard reagent to give the corresponding tetraorganogermanes R4Ge while the less reactive complex 3 leads to the functional triorganogermanes R3GeX. Tetraorganogermanes can also be prepared from complex 2b by reaction with organic bromides in the presence of Mg (Barbier reaction). The influence of Cp2TiCl2 and MgBr2 on the reactivity of Grignard reagents with these complexes was also investigated: in both cases formation of triorganogermanes was favored.
