1,2-Di(prop-2-enyl)-tetramethyldisilane (also known as 1,2-diallyltetramethyldisilane) is a member of the α,ω-diallylpermethyloligosilane family, synthesized via the reaction of α,ω-dichloropermethyloligosilanes (specifically Cl(Me2Si)2Cl) with allylmagnesium chloride. It features a disilane backbone with two allyl (prop-2-enyl) groups attached to the silicon atoms, each of which is also substituted with methyl groups. 1,2-Di(prop-2-enyl)-tetramethyldisilane was studied for its fragmentation behavior under electron impact ionization, demonstrating its relevance in mass spectrometric analysis of organosilicon compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 18645-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18645-49:
(7*1)+(6*8)+(5*6)+(4*4)+(3*5)+(2*4)+(1*9)=133
133 % 10 = 3
So 18645-49-3 is a valid CAS Registry Number.

Synthesis and mass spectrometric study of α,ω- diallylpermethyloligosilanes

Larkin,Pleshkova,Kononova,Chernyavskaya,Chernyavskii

, p. 2224 - 2228 (2004)

Representatives of the homologous series of α,ω- diallylpermethyloligosilanes were synthesized for the first time by the reaction of α,ω-dichloropermethyloligosilanes Cl(Me2Si) nCl (n = 2-6) with allylmagnesium chloride. Fragmentation of α,ω-diallylpermethyloligosilanes under electron impact ionization was studied by mass spectrometry.

Homoconjugation in allyl silicon derivatives

Osadchev,Pushkarev,Nikitina,Shamanin,Skorokhodov

, p. 1378 - 1382 (2007/10/03)

New diallyl derivatives of mono- and disilane were obtained and characterized. Fluorescence, 1H, C, and 29Si NMR, as well as IR and Raman spectroscopy were used to show the presence of intramolecular donor-acceptor β-coupling between the silicon atom and the allyl groups, which is realized directly through space by the homoconjugation mechanism (i.e. direct conjugation between vacant 3d orbitals of the silicon atom and the allyl π bonds, not involving σ orbitals of the allyl methylene groups).
