Allenyltrimethylstannane, also known as 2-propenyltrimethylstannane, is an organotin compound with the chemical formula (CH3)3SnCH=CHCH3. It is a colorless liquid that is sensitive to air and moisture. allenyltrimethylstannane is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction, a type of cross-coupling reaction. Allenyltrimethylstannane is also employed in the synthesis of various organic compounds, such as natural products and pharmaceuticals, due to its ability to act as a nucleophile and participate in various reactions, including addition, substitution, and elimination processes. It is important to handle allenyltrimethylstannane with care, as organotin compounds can be toxic and have environmental and health concerns.

4104-88-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4104-88-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4104-88:
(6*4)+(5*1)+(4*0)+(3*4)+(2*8)+(1*8)=65
65 % 10 = 5
So 4104-88-5 is a valid CAS Registry Number.

SYNTHESIS OF (Z)-1,2-BIS(TRIMETHYLSTANNYL)-1-ALKENES BY PLATINUM-CATALYSED ADDITION OF HEXAMETHYLDISTANNANE TO 1-ALKYNES

Mitchell, T. N.,Amamria, A.,Killing, H.,Rutschow, D.

, p. C45 - C47 (1983)

Addition of hexamethyldistannane to 1-alkynes in the presence of tetrakis(triphenylphosphine)palladium yields the title compounds, which can be photo-chemically isomerised to the corresponding (E)-distannylalkenes.
