Disilane, 1,2-difluoro-1,1,2,2-tetramethyl-, also known as 1,1,2,2-tetramethyl-1,2-difluoro-1,2-disilane, is a chemical compound with the molecular formula C4H12F2Si2. It is a colorless, volatile liquid that is sensitive to air and moisture. Disilane, 1,2-difluoro-1,1,2,2-tetramethyl- is a derivative of disilane, where two hydrogen atoms are replaced by fluorine atoms, and two methyl groups are attached to each silicon atom. It is used as a precursor in the synthesis of various organosilicon compounds and as a reagent in the preparation of silylating agents. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from heat and light.

661-68-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 661-68-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 661-68:
(5*6)+(4*6)+(3*1)+(2*6)+(1*8)=77
77 % 10 = 7
So 661-68-7 is a valid CAS Registry Number.

Photoinduced electron-transfer reaction of 7,8- disilabicyclo[2.2.2]octa-2,5-dienes

Kako,Hatakenaka,Kakuma,Ninomiya,Nakadaira,Yasui,Iwasaki,Wakasa,Hayashi

, p. 1133 - 1136 (2007/10/03)

9,10-Dicyanoanthracene-sensitized irradiation of 7,8- disilabicyclo[2.2.2]octa-2-5-dienes1-3 in the presence of MeOH resulted in the formation of dimethoxydisilanes and the corresponding aromatic compounds. A stepwise mechanism involving C-Si bond cleavage by MeOH is proposed.

Preparative electrochemical oxidation of cyclic peralkylsilanes
