Stannane, dimethylbis(phenylethynyl)-, also known as dimethyldistannane or bis(phenylethynyl)dimethylstannane, is a chemical compound with the molecular formula C16H14Sn. It is a colorless, crystalline solid that is soluble in organic solvents. This organotin compound features a central tin atom bonded to two methyl groups and two phenylethynyl groups, which are ethynyl groups attached to a phenyl ring. It is used in various applications, including as a precursor in the synthesis of other organotin compounds, in polymer chemistry, and as a reagent in organic synthesis. Due to its potential toxicity and environmental impact, it is important to handle Stannane, dimethylbis(phenylethynyl)- with care and in accordance with safety regulations.

3912-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3912-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3912-89:
(6*3)+(5*9)+(4*1)+(3*2)+(2*8)+(1*9)=98
98 % 10 = 8
So 3912-89-8 is a valid CAS Registry Number.

Transmetalation of tetraalkynyltin compounds with Grignard reagents: Access to mono- and dialkyltin products

Jaumier, Pascale,Jousseaume, Bernard,Lahcini, Mohammed

, p. 402 - 404 (2007/10/03)

Monoalkyltrialkynyl- and dialkyldialkynyltin compounds can be selectively synthesized by transmetalation of tetraalkynyltin compounds with Grignard reagents; an example is given in Equation (1). This reaction provides a route to mono- and dialkyltin compounds that avoids the use of strongly electrophilic reagents. The labile tin-alkynyl bonds allow the transmetalation products to be converted into alkyltin oxides, chlorides, and alkoxides.
