General Description

Vinylphenyldimethylsilane is a chemical compound with the formula C10H14Si. It is a colorless liquid that is commonly used as a precursor in the synthesis of various organosilicon compounds. It contains a vinyl group, which makes it useful for polymerization reactions to produce silicone resins, rubbers, and other materials. Vinylphenyldimethylsilane is also employed in the production of specialty coatings, adhesives, and sealants due to its ability to improve the adhesion and flexibility of these materials. Additionally, it is utilized as a crosslinking agent in the formulation of modified polymers and as a reactive intermediate in the synthesis of pharmaceuticals and other organic compounds. Overall, vinylphenyldimethylsilane is an important chemical in the field of organosilicon chemistry with a wide range of industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1125-26-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1125-26:
44 % 10 = 4
So 1125-26-4 is a valid CAS Registry Number.

Catalytically active, recyclable polymeric titanocene disks: A batch-flow reactor

Berget, Patrick E.,Schore, Neil E.

, p. 8869 - 8871 (2005)

Dichlorotitanocene bound within porous polystyrene disks catalyzes the coupling of vinylmagnesium chloride and chlorosilanes to form 1,4-bis(silyl)-2-butenes. A simple batch-flow reactor permits catalyst reuse by repeated addition of fresh reagents and de

New polymers derived from 4-vinylsilylbenzocyclobutene monomer with good thermal stability, excellent film-forming property, and low-dielectric constant

Yang, Junxiao,Liu, Shangchun,Zhu, Fanghua,Huang, Yawen,Li, Bo,Zhang, Lin

, p. 381 - 391 (2011)

A series of benzocyclobutene (BCB) polymers derived from a new readily available monomer, 4-(1′,1′-dimethyl-1′-vinyl) silylbenzocyclobutene (4-DMVSBCB), were conveniently prepared by radical and anionic polymerization. The homo- and co-polymerization results show that the reactivity of 4-DMVSBCB in anionic polymerization is relatively higher compared with radical polymerization. The molecular weight of 4-DMVSBCB polymers and content of 4-DMVSBCB can be controlled by anionic copolymerization. The introduction of rigid and crosslinkable BCB building blocks in side chains and carbosilanes in molecule gives rise to insulating materials with good film-forming property, smooth and flat film surface, and low-dielectric constants of 2.41-2.45, as preserving good thermal stability.

Copper-Catalyzed Asymmetric Hydroallylation of Vinylsilanes

Guo, Xiaobing,Niu, Junbo,Wang, Simin,Xiong, Tao,Zhang, Qian,Zhang, Qiao

A copper-catalyzed asymmetric hydroallylation of readily available vinylsilanes with allylic phosphates in the presence of hydrosilane was developed. These transformations can be performed under mild reaction conditions and provide the useful chiral organ

Cross-Electrophile C(sp2)?Si Coupling of Vinyl Chlorosilanes

Duan, Jicheng,Kang, Shaolin,Liu, Xue-Yuan,Qi, Liangliang,Shu, Xing-Zhong,Wang, Ke,Xu, Guang-Li

supporting information, p. 23083 - 23088 (2020/12/09)

The cross-electrophile coupling has become a powerful tool for C?C bond formation, but its potential for forging the C?Si bond remains unexplored. Here we report a cross-electrophile Csp2-Si coupling reaction of vinyl/aryl electrophiles with vinyl chlorosilanes. This new protocol offers an approach for facile and precise synthesis of organosilanes with high molecular diversity and complexity from readily available materials. The reaction proceeds under mild and non-basic conditions, demonstrating a high step economy, broad substrate scope, wide functionality tolerance, and easy scalability. The synthetic utility of the method is shown by its efficient accessing of silicon bioisosteres, the design of new BCB-monomers, and studies on the Hiyama cross-coupling of vinylsilane products.

Thieme Chemistry Journals Awardees - Where Are They Now? Titanium-Catalyzed Hydroaminoalkylation of Vinylsilanes and a One-Pot Procedure for the Synthesis of 1,4-Benzoazasilines

Lühning, Lars H.,Rosien, Michael,Doye, Sven

supporting information, p. 2489 - 2494 (2017/11/04)

Vinylsilanes undergo intermolecular alkene hydroaminoalkylation with secondary amines in the presence of a titanium mono(aminopyridinato) catalyst to give the branched hydroaminoalkylation products with high regioselectivity. Corresponding reactions of a suitable (2-bromophenyl)vinylsilane combined with a subsequent intramolecular Buchwald-Hartwig amination result in the development of an elegant one-pot procedure for the synthesis of 1,4-benzoazasilines.
