"Tin, 2-butynyltriphenyl-" is a chemical compound with the formula C26H21Sn and the molecular weight of 421.12 g/mol. It is an organotin compound, which is a type of organometallic compound that contains a carbon-tin bond. This specific compound features a tin atom bonded to a 2-butynyl group (a three-carbon chain with a triple bond) and three phenyl groups (benzene rings). Organotin compounds are known for their wide range of applications, including as catalysts, stabilizers, and biocides. "Tin, 2-butynyltriphenyl-" is a colorless to pale yellow solid and is sensitive to air and moisture, which means it should be stored under an inert atmosphere to prevent degradation. Due to its organometallic nature, it may have potential applications in various chemical processes and materials science, but it is important to handle it with care due to its potential toxicity.

4104-93-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4104-93-2 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 4104-93:
(6*4)+(5*1)+(4*0)+(3*4)+(2*9)+(1*3)=62
62 % 10 = 2
So 4104-93-2 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.
