Vinyl triethoxy silane

Sengupta showed that the reaction of bis-arenediazonium salt 91 with vinyl(triethoxy)silane 92 afforded poly(phenylene-vinylene) 93. Although the reaction apparently proceeds through the Heck reaction mechanism, which is described in Section 11.19.4, a part of the step-growth reaction is indeed a transformation of the carbon-silicon bond of 92 to the carbon-carbon bond (Equation (44)). 

Vinyl triethoxy silane (VTES). The vinyltriethoxy silane films obtained on silica were more oleophobic (lower y0 values) and more hydrophobic (higher 0H2o values) than the films formed from corre-... 

Silanes used for treatment dimethyldiethoxy silane, 3-(methacryloxy) propyltrimethoxy silane, vinyl triethoxy silane, amino silane. Silane coating was estimated to be 0.2 wt%. Treatment with epoxy silane has been used followed by PS-maleic anhydride grafting through amine spacer.

The TG profiles of vinyl triethoxy silane-methyl methacrylate (VTES-MMA) copolymers in N2 have been reported to be similar to that of PMMA [a.l85]. However, the initial decomposition temperature (IDT) of the copolymers decreased with increasing VTES content in the copolymer. This behaviour was attributed to the decrease in the molecular weight of these copolymers during degradation. A similar tendency for TG was also reported for styrene-siloxane block copolymers synthesised with a living anionic initiator [a.l86]. 

Figure 20. Molecular dynamics simulations of the positional arrangement of fully hydrolyzed oiganosilane molecules on an FeOOH substrate, obtained using the Cerius- Sorption package (a) glycidoxypropyl trimethoxysilane the silane head is at the right-hand end of the molecule (b) y-aminopropyl tri-ethoxysilane the silane head is at the left-hand end of the molecule (c) vinyl-triethoxy silane the silane head of the molecule is adjacent to the FeOOH surface. The scale bar is 0.2 nm. This figure was produced using the original (color) computer graphics files obtained by Davis 1146).

Aryl cyanides add to norbornene and norbornadiene under nickel catalysis to give (2/U,35 )-3-aryl-2-cyanobicyclo[2.2.11heptanes and (2/U,3.S )-3-aryl-2-cyanobicy-clo[2.2.1]hept-5-enes in good yields with a broad substrate scope. On the other hand, the reaction of an aryl cyanide with triethoxy(vinyl)silane gives a Heck-type arylation product, suggesting the arylnickelation pathway in the catalytic cycle.68... 

Of course there are many other reagents used to attach a double bond to polyether polyols such as chloromethyl styrene (mixture of meta and para isomers), glycidyl acrylate and methacrylate [48] triethoxy or trimethoxy vinyl silanes [54]. 

Aryl bromides or iodides react with di- or monochloro(vinyl)silanes or triethoxy(vinyl)silane in the presence of Et3N and palladium catalyst to give /S-arylvinylsilanes in moderate to excellent yields. In contrast to the simple silyl substituent, the presence of the electron-withdrawing group on sihcon is essential to avoid the elimination of the silyl group. No silver ion is necessary in these examples . The palladium-catalyzed reaction of aryldiazonium tetrafluoroborates with vinylsilanes gives a mixture of terminal and internal vinylsilanes together with styrenes. ... 

Under basic conditions the hydrolysis of alkoxy groups takes place during the silane application process, and generally occurs in a stepwise fashion. Except for aminosilanes, however, it is usual to employ acid conditions. The rate of hydrolysis of alkoxy groups decreases with an increase in their size, for instance FTIR evidence indicates that vinyl tri-methoxysilane hydrolyses almost eight times as quickly as the triethoxy equivalent. The glass surface is likely to become covered with several monolayers of hydrolysed silane. 

A solution of the Grubbs catalyst (the first generation, 0.10 g, 0.12 mmol) in benzene (10 mL) was prepared in a Schlenk tube equipped with a condenser. To this sollution styrene (1.87 g, 18 mmol), and triethoxy(vinyl)silane (1.16 g, 6.1 mmol) are added, and the resulting mixture is stirred at rt for 6 h with a gentle flow of argon to remove coproduced ethylene. The title compound is isolated by distillation under vacuum (94-98 °C at 1 mmHg) in 83% yield. ...
