3-AminopropylsilatraneTGASilatraneSome new silatranes containing an azomethine group as coordinating system in the axial chain are reported. This system is introduced into the chain by the treatment of 3-aminopropylsilatrane with different carbonyl compounds like acetylacetone (1), 2-acetylphenol (2...
3-Aminopropyltrialkoxysilane was reacted with triethanolamine in 1:1 molar ratio, either in bulk, in the presence of metallic sodium, or in a solvent mixture. 1-(3-Aminopropyl)silatrane in carbamate form or having free amine groups was obtained. The latter was reacted with 2-...

New functionalized silatranes were synthesized by the reaction of 3-aminopropylsilatrane with urea, thiourea, guanidine, acetamide, acetylguanidine, and aminoguanidine. These silatranes were used to modify silica gel. The sorption activity of the modified silica gel towards the ions of the rare-...
3-Aminopropyltriethoxysilane and -silatrane readily enter into the Michael aza reaction with various acrylates. Depending on the ratio of the reagents, Michael mono- or diadducts, containing functional groups (triethoxysilyl, carbonyl, nitrile, amino, etc.), are formed. These compounds have been ...
Silatranes bearing an amide group in the axial chain have been synthesized by the reaction of 1-(3-aminopropyl)silatrane with arylchalcogenylacetic acids (Het)ArYCH2CO2H [(Het)Ar = 2-MeC6H4, 4-Cl-2-MeC6H3, 4-ClC6H4, 3-indolyl; Y = O, S], and their structures have been ...

The features of the phenomenon of nuclear magnetic resonance in paramagnetic systems are considered. Specific character of detection of high-resoluton NMR spectra modified by hyperfine coupling is analyzed. Examples of the use of specific features of nuclear magnetic resonance in paramagnetic complexes ...
