Silane, methylbis(phenylmethyl)-, also known as bis(benzyl)methylsilane or (CH3)2Si(C6H5CH2)2, is an organosilicon compound characterized by a silicon atom bonded to two benzyl groups and one methyl group. This colorless liquid is a versatile reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a protecting group for alcohols. It is also used in the synthesis of silyl ethers and as a coupling agent in the formation of silyl enol ethers. Due to its reactivity and stability, it plays a significant role in various chemical transformations, making it an important intermediate in the field of organosilicon chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 1631-71-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1631-71:
(6*1)+(5*6)+(4*3)+(3*1)+(2*7)+(1*1)=66
66 % 10 = 6
So 1631-71-6 is a valid CAS Registry Number.

Reactivity of Hypervalent Species: Reactions of Anionic Penta-Coordinated Silicon Complexes towards Nucleophiles

Boudin, Alain,Cerveau, Genevieve,Chuit, Claude,Corriu, Robert J. P.

, p. 101 - 106 (2007/10/02)

The reactivity of anionic penta-coordinated silicon complexes 4-O)2>-Na+ 1 with nucleophilic reagents has been studied. 1 can be reduced to organosilanes RSiH3 by metallic hydrides.Reactions with an excess of Grignard or organolithium reagents (R'MgX or R'Li) gave tetraorganosilanes RSiR'3.When only two molar equivalents of Grignard reagents (R'MgX) or lithium reagents (R'Li) are added to complexs 1 functional silanes RR'2SiX can be prepared.
