The hydrolysis and dynamics of silane coupling agents have been probed using nuclear magnetic resonance (NMR) spectroscopy. The hydrolysis of γ-aminopropyltrimethoxysilane and γ-aminopropyltriethoxysilane were studied using proton NMR spectroscopy. The rates of hydrolysis were dependent on the water and silane coupling agent concentration as well as their chemical nature. The methoxy-substituted silane hydrolyzed much faster than the ethoxy-substituted one. The molecular motion of γ-aminopropylsilane-d2 immobilized on a silica surface and as the bulk polymerized siloxane were characterized by 2H solid-echo NMR techniques. It was found that the motion of the silane coupling agent on silica was more restricted than in the condensed polymer. Deuterium oxide exchange experiments also showed that the motion of deuterons on the amino group is much faster than those of the deuterons on the methylene group in silane coupling agents. © 1990.

This research project examines the transport of ions through porous alumina membranes with channels of ̃200 nanometers in diameter. The test molecule is the permeate anion 1,5-naphthalene disulfonate (NDS2-), which as absorbance in the ultraviolet range and also exhibits fluorescence. This allows direct examination of transport by utilizing ultraviolet-visible spectroscopy as well as fluorescence spectroscopy. Adding substituents through strong alumina-silane linkages further modifies all the surfaces of the alumina nanotube membranes. Membranes are soaked in solutions containing either octadecyl trimethoxysilane (ODTMS) or isobutyl trimethoxysilane (IBTMS). Ion transport across the membrane treated with the hydrophobic octadecyl trimethoxysilane was hindered significantly, while the membranes exposed to a short alkyl chain isobutyl trimethoxysilane demonstrated only a slight blockage of ion transport. In both cases, addition of an ionic surfactant dodecyl benzenesulfonate (DBS) and also cationic drug

Reed and wheat straw particleboards bonded with urea formaldehyde (UF) resin were manufactured from two different material configurations (i.e., fine and coarse particles). The board densities were in the range of 0.550-.90g/cm3. The effects of particle size and board density on the board properties were examined. The properties of particleboard produced from fine particles were better than those made from coarse particles. An increase in board density resulted in a corresponding improvement in the board properties. The properties of OF bonded reed and wheat straw particleboards were relatively lower than those of commercial particleboards. Three silane coupling agents were used to improve the bondability between the reed and wheat particles and OF resin. Results of this study indicate that all the board properties were improved by the addition of silane coupling agent. The degree of improvement achieved from each coupling agent was different; epoxide silane was found to be more effective for reed straw

AU - Rock, Christopher L.. AU - Trovitch, Ryan. PY - 2019/1/1. Y1 - 2019/1/1. N2 - The phosphine-substituted α-diimine Ni precursor, ( Ph 2 PPr DI)Ni, has been found to catalyze alkene hydrosilylation in the presence of Ph 2 SiH 2 with turnover frequencies of up to 124 h −1 at 25 °C (990 h −1 at 60 °C). Moreover, the selective hydrosilylation of allylic and vinylic ethers has been demonstrated, even though ( Ph 2 PPr DI)Ni is known to catalyze allyl ester C-O bond hydrosilylation. At 70 °C, this catalyst has been found to mediate the hydrosilylation of ten different gem-olefins, with turnover numbers of up to 740 under neat conditions. Prior and current mechanistic observations suggest that alkene hydrosilylation takes place though a Chalk-Harrod mechanism following phosphine donor dissociation. AB - The ...

The chloro and azido complexes trans-[PdCl(4-C5NF4)(PiPr(3))(2)] ( 3) and trans-[Pd(N-3)(4-C5NF4)(PiPr(3))(2)] ( 4) can be prepared by reaction of [PdF(4-C5NF4)(PiPr(3))(2)] ( 2) with Et3SiCl or MeSiN3, respectively. In contrast, reactions of 2 with Ph3SiH or Me2FSiSiFMe2 give the products of reductive elimination 2,3,5,6-tetrafluoropyridine ( 5) or 4-(fluorodimethylsilyl) tetrafluoropyridine ( 6) as well as [Pd(PiPr(3))(2)] ( 1). In a catalytic experiment, pentafluoropyridine can be converted with Ph3SiH into 5 in 62% yield, when 10% of 2 is employed as catalyst. Treatment of trans-[PdF(4-C5NF4)(PiPr(3))(2)] ( 2) with Bu3SnCH=CH2 in THF at 50 degrees C results in the formation of [Pd(PiPr(3))(2)] ( 1) and 4- vinyltetrafluoropyridine ( 7). Complex 2 is also active as a catalyst towards a Stille cross-coupling reaction of pentafluoropyridine with Bu3SnCH= CH2 to give 4-vinyltetrafluoropyridine ( 7) with a TON of 6.

TY - JOUR. T1 - Homogeneous gold-catalyzed hydrosilylation of aldehydes. AU - Lantos, Diána. AU - Contel, María. AU - Sanz, Sergio. AU - Bodor, A.. AU - Horváth, I.. PY - 2007/4/1. Y1 - 2007/4/1. N2 - The catalytic hydrosilylation of aldehydes in the presence of PBu3 modified Au(I)-complexes was investigated. In situ IR and NMR experiments have revealed that both, the ligand PBu3 and the substrate aldehyde play an important role in stabilizing the gold catalyst and/or forming the catalytically active species. In their absence the reducing power of silane destabilizes the gold (I) catalyst giving rise to gold clusters or particles. Several side reactions involving water and oxygen were also investigated. A plausible reaction pathway as an alternative to the well-accepted mechanism for the transition-metal homogeneously catalyzed hydrosilylation of aldehydes has been proposed to accommodate the experimental observations.. AB - The catalytic hydrosilylation of aldehydes in the presence of PBu3 ...

A comparative survey of published work on the reactions of organic derivatives of the Group IVB elements has been made, and the function of these elements in such reactions is discussed. The influence of the trimethylsilyl- and trimethyl- -germyl- substituents on the strengths of some carboxylic acids indicates that the inductive electron-releasing effect is slightly greater, and steric effects consider- -ably less, in the latter group. The alkaline cleavage of numerous tetra-organo- -silanes, -germanes, and -stannanes has been examined. The absolute and relative rates vary widely with the constitution of the compounds, but the germanes are generally much less reactive than the silanes, which are rather less reactive than the stannanes. The tetraorgano-stannanes are often less reactive than might be anticipated. The results are interpreted in terms of decreasing availability of the vacant d-orbitals for transition- state stabilisation as we descend Group IVB. The trimethylaralkyl-germanes and ...

Surface modification of argon-plasma-pretreated poly(tetrafluoroethylene) (PTFE) film via UV-induced graft copolymerization with glycidyl methacrylate (GMA) was carried out first. Reactive adsorption of γ-aminopropyltriethoxysilane (APS) onto the GMA graft-copolymerized PTFE (GMA-g-PTFE) film surface was performed by the simple immersion of the film in the APS solution. The adsorption process was studied as a function of the APS concentration, the immersion time of the graft-modified PTFE film in the APS solution, and the washing protocol. The chemical composition and morphology of the silane-modified surfaces were characterized by X-ray photoelectron spectroscopy and atomic force microscopy, respectively. The performance of the silane-modified PTFE surface in adhesion promotion was investigated. The T-peel adhesion strength of the evaporated Cu on the PTFE film with the reactively adsorbed organosilane increased significantly to about 12.15 N/cm. This adhesion strength was more than twice that ...

An aromatic composition comprises aromatic substances that are encapsulated and/or clathrated in a matrix of polymer. The polymer includes an inorganic polymer produced from metal alkoxides; a conjugated polymer produced from metal alkoxides and silane coupling agents; and a conjugated polymer produced from metal alkoxides, silane coupling agents, and organic monomers. The aromatic composition has slow-release characteristics, so that the aromatic substances are released over a long period of time. In a method for the production of the aromatic composition, a catalyst for sol-gel methods that comprises an acid or its anhydride and an organic base, and if necessary, irradiation with ultraviolet light and/or an electron beam are used for making the polymer.
Coating compositions and methods for applying reactive silanol coating compositions having electron deficient surfaces when cured wherein organic radical groups from the silanes are forced to the surface of the coating. The interpenetrating silicon-oxygen structure below the surface skews the electron cloud downward creating a net positively charged surface which is hydrophobic and oleophobic to repel contaminants by discouraging light hydrogen bonding. The surface is also extremely tight and thereby absent nutrients for microorganisms, discourages organic growth. These unique qualities provide cleanliness solutions for automotive and marine applications, including substrates subjected to elevated temperatures typically destructive to organic coatings (paints). Substrate examples are: brakes to repel brake dust on wheels; coating of engines and engine accessories, high-temperature exhausts/stacks/eductors, and engine compartments; automotive, architectural, industrial, and marine exterior

A reaction product including the ligand component and a metal precursor is prepared by combining the ligand component with the metal precursor. An activated reaction product is formed by activating the reaction product as a hydrosilylation catalyst.
Self-assembled monolayers (SAM) of organic molecules are molecular assemblies formed spontaneously on surfaces by adsorption and are organized into more or less large ordered domains. In some cases molecules that form the monolayer do not interact strongly with the substrate. This is the case for instance of the two-dimensional supramolecular networks of e.g. Perylenetetracarboxylic dianhydride (PTCDA) on gold or of e.g. porphyrins on highly oriented pyrolitic graphite (HOPG). In other cases the molecules possess a head group that has a strong affinity to the substrate and anchors the molecule to it. Such a SAM consisting of a head group, tail and functional end group is depicted in Figure 1. Common head groups include thiols, silanes, phosphonates, etc. SAMs are created by the chemisorption of "head groups" onto a substrate from either the vapor or liquid phase followed by a slow organization of "tail groups". Initially, at small molecular density on the surface, adsorbate molecules form either ...

There are no reliable ready biodegradation data available for triethoxy(methyl)silane, therefore good quality data for the analogue substance, triacetoxyethylsilane (CAS 17689 -77 -9), have been read across. Both substances hydrolyse to structurally-related silanol hydrolysis products, methylsilanetriol and ethylsilanetriol. The other hydrolysis products being ethanol and acetic acid, respectively. Therefore, triethoxymethylsilane hydrolyzes rapidly into ethanol which is readily biodegradable and methylsilanetriol which is not. Both triethoxy(methyl)silane and triacetoxyethylsilane are within an analogue group of substances within which, in general, there is no evidence of any significant biodegradation once biodegradation of alkoxy/acetoxy groups has been taken into account. It is therefore considered valid to read-across the results for triacetoxyethylsilane to fill the data gap for the registered substance. This wider analogue group for the ready biodegradability endpoint consists of a number ...
