Synthesis
The apparatus of Example B was charged with 148.8 g (1.2 mol) of 1-vinyl-3,4-epoxycyclohexane, 1.3 g of a carboxylic acid promoter, and 0.15 ml of 10% chloroplatinic acid catalyst solution. The flask contents were heated to 89° C. and dropwise addition of 122.8 g {[1.0 mol) of trimethoxysilane was begun. The reaction temperature was controlled at 90°-95° C. with an ice bath. Reaction was maintained at that temperature for half an hour after completion of addition, which took 18 minutes. Analysis by gas chromatography showed a yield of 90% of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane. This example demonstrates a standard preparation of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane using commercial chloroplatinic acid.
Check Digit Verification of cas no
The CAS Registry Mumber 3388-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,8 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3388-04:
(6*3)+(5*3)+(4*8)+(3*8)+(2*0)+(1*4)=93
93 % 10 = 3
So 3388-04-3 is a valid CAS Registry Number.

Alkene Hydrosilylation on Oxide-Supported Pt-Ligand Single-Site Catalysts

Heterogeneous single-site catalysts (SSCs), widely regarded as promising next-generation catalysts, blend the easy recovery of traditional heterogeneous catalysts with desired features of homogeneous catalysts: high fraction of active sites and uniform metal centers. We previously reported the synthesis of Pt-ligand SSCs through a novel metal-ligand self-assembly method on MgO, CeO2, and Al2O3 supports (J. Catal. 2018, 365, 303–312). Here, we present their applications in the industrially-relevant alkene hydrosilylation reaction, with 95 % yield achieved under mild conditions. As expected, they exhibit better metal utilization efficiency than traditional heterogeneous Pt catalysts. The comparison with commercial catalysts (Karstedt and Speier) reveals several advantages of these SSCs: higher selectivity, less colloidal Pt formation, less alkene isomerization/hydrogenation, and better tolerance towards functional groups in substrates. Despite some leaching, our catalysts exhibit satisfactory recyclability and the single-site structure remains intact on oxide supports after reaction. Pt single-sites were proved to be the main active sites rather than colloidal Pt formed during the reaction. An induction period is observed in which Pt sites are activated by Cl detachment and replacement by reactant alkenes. The most active species likely involves temporary detachment of Pt from ligand or support. Catalytic performance of Pt SSCs is sensitive to the ligand and support choices, enabling fine tuning of Pt sites. This work highlights the application of heterogeneous SSCs created by the novel metal-ligand self-assembly strategy in an industrially-relevant reaction. It also offers a potential catalyst for future industrial hydrosilylation applications with several improvements over current commercial catalysts.
An Easily Accessed Nickel Nanoparticle Catalyst for Alkene Hydrosilylation with Tertiary Silanes

The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni(OtBu)2?x KCl. The catalyst exhibits high activity for anti-Markovnikov hydrosilylation of unactivated terminal alkenes and isomerizing hydrosilylation of internal alkenes. The catalyst can be applied to synthesize a single terminal alkyl silane from a mixture of internal and terminal alkene isomers, and to remotely functionalize an internal alkene derived from a fatty acid.

, (2008/06/13)
In a process for the preparation of epoxy group-containing alkoxy silanes by hydrosililation of a terminally unsaturated epoxy compound with a hydro-alkoxy silane using a platinum catalyst, the improvement comprising carrying out the hydrosililation in the presence of an alcohol. By this process formation of the internally sililated isomer can be suppressed and the desired terminally sililated poduct can be produced at an approximately 100% selectivity.
