Triphenyl-butadien-(1,2)-yl-(1)-zinn, also known as triphenyl(1,2-butadienyl)zinc, is an organozinc compound with the chemical formula C20H16Zn. It is a colorless to pale yellow solid, soluble in organic solvents, and is sensitive to air and moisture. Triphenyl-butadien-(1,2)-yl-(1)-zinn is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. It is synthesized by the reaction of triphenylzinc with 1,2-butadiene. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from light and heat.

4104-92-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4104-92-1 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, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4104-92:
(6*4)+(5*1)+(4*0)+(3*4)+(2*9)+(1*2)=61
61 % 10 = 1
So 4104-92-1 is a valid CAS Registry Number.

REGIO- AND STEREO-CHEMICAL FEATURES OF THE STANNYLCOPPER(I)-INDUCED SUBSTITUTION IN PROPARGYLIC SUBSTRATES

Ruitenberg, K.,Westmijze, H.,Meijer, J.,Elsevier, C. J.,Vermeer, P.

, p. 417 - 422 (2007/10/02)

Stannylcopper(I) species, R3SnCu and 2CuLi, preferentially convert propargylic substrates, R1CCCR2R3X (X=Br, MeCO2, MeS(O)O or MeSO3) into allenes R3Sn(R1)C=C=CR2R3.Only when the group R1 causes much greater steric hindrance than with R2 and R3 is the acetylenic product R1CCCR2R3SnR3 formed.The stereochemical course of the allene formation has been studied in both the steroid and non-steroid series, and found to be mainly or exclusively anti.
