The transimidization reaction between phthalic anhydride and (3-aminopropyl)triethoxysilane was carried out using 2-(3-methylpyridin-2-yl)isoindoline-1,3-dione 1 to synthesize N-(triethoxysilylpropyl)phthalimide 2 in good yield. New silatranes 3 and 4 containing phthalimide as exocyclic group were prepared by the transesterification reactions of N-(triethoxysilylpropyl)phthalimide 2 with triethanolamine and trisisopropanolamine respectively. All the compounds were characterized by elemental analysis, spectroscopic techniques and thermogravimetric analysis. The compounds 3 and 4 were also characterized by X-ray diffraction analysis. The electronic absorption spectra of compounds 3 and 4 were studied in six solvents with different polarities. N-(silatranylpropyl)phthalimides were evaluated for the preliminary antimicrobial activity using broth microdilution method.

(Dicyclopentadiene) platinum(II) dichloride was found to be an efficient hydrosilylation catalyst (homogeneous) upon a wide variety of functionalized alkenes and alkenes terminated with chemical moieties (diphenyl amino-, N-carbazol- and N-isoindoline-1,3-dione-). It is noteworthy that the hydrosilylation of aminated alkenes with triethoxysilane exhibited the yield of over 70% and the selectivity (γ-isomer/β-isomer) of more than 3/1. Due to steric hindrance lowering Markovnikov probability, the alkenes with big terminal moieties (diphenyl amino-, N-carbazol- and N-isoindoline-1,3-dione-) presented the high ratio of anti-Markovnikov isomers. The strategy of the hydrosilylation of the protected diamino chelating alkene was developed.

Paragraph 0025, (2016/10/31)
A preparation method of a modified silane coupling agent comprises: (1), dissolving mono-anhydride or tetracid dianhydride in glacial acetic acid, adding allylamine according to a molar ratio of the mono-anhydride or tetracid dianhydride to the allylamine being 1:1 or 1:2, stirring and reflowing for 3-24 h, adding water, filtering, washing, and drying to obtain an imide product; (2), dissolving the imide product in an aprotic solvent of medium polarity, adding 0.2 ml or 0.35 ml of a catalyst and trialkoxysilane according to a molar ratio to the imide product being 1:1 or 2:1, and reacting at 50-70 DEG C for 5-48 h, distilling at reduced pressure to remove a low-boiling-point fraction to obtain a product.Least catalyst is used at the premise of ensuring optimal catalytic efficiency so that lowest production cost is achieved.

, (2008/06/13)
The invention relates to a new class of alkoxy silane compounds of the following general formula: wherein R is aliphatic or aromatic having from 1 to about 15 carbon atoms and R' comprises a hydrolyzable alkoxy functionality. These compounds are particularly useful as adhesion promoters when used with adhesives such as, for example, phenylethynyl terminated polyamide or polysufide adhesives. The invention also relates to a method of synthesizing the alkoxy silane compounds defined above.
