“…The coordination polyhedron of the silicon atom in complex I is a trigonal bipyramid that is common for silatranes [5]. The length of the N3→Si coordination bond of 2.089(5) Å is close to that observed in the 1-hydrosilatrane (2.071 Å) [6], N-(1-silatranylmethyl)imidazole (2.088 Å) [7], and -benzimidazole (2.088 Å) [8] moleculеs and coincides with this bond length in N-(1-silatranylmethyl) pyrrole (2.089 Å) [9], 2-(1-silatranylmethyl)-1,2,3-benzotriazole (2.089 Å) [10], differing from 1-(2′-benzothiazolylthiomethyl)silatrane (2.100 Å) [2] by only 0.011 Å.…”

The crystal and molecular structure of the complex of 2-(1-silatranylmethylthio)-4,5-benzo-1,3-thiazole with СоСl 2 and MeCN (I) is determined by single crystal X-ray diffraction. The geometry of the silatranylmethyl moiety in complex I is compared to the geometry of 1-(2′-benzthiazolylthiomethyl) silatrane. Molecular packing in the crystal is analyzed. Keywords: 2-(1-silatranylmethylthio)-4,5-benzo-1,3-thiazole, acetonitrile, molecular structure, single crystal X-ray diffraction analysis.Using single crystal X-ray diffraction, we have previously studied the crystal and molecular structure of the complex of 2-( ethylthio)-4,5-benzo-1,3-thiazole with СoCl 2 of the composition 2:1 at room temperature [1] and 1-(2′-benzthiazolylthiomethyl)silatrane at 130 K [2]. In continuation of these studies, we investigated the complex of 2-(1-silatranylmethylthio)-4,5-benzo-1,3-thiazole with СоСl 2 and MeCN (I).Complex I is remarkable not only by the presence of the silatranylmethyl group, which is characterized by a high electron donating effect and bulkiness, but also by the involvement of N 2 nitrogen belonging to MeCN in the coordination sphere of the cobalt atom.Experimental. Complex of 2-(1-silatranylmethylthio)-4,5-benzo-1,3-thiazole with CoCl 2 (II). 0.45 g (1.3 mmol) of 2-(1-Silatranylmethylthio)-4,5-benzo-1,3-thiazole III and 0.17 g (1.3 mmol) of anhydrous CoCl 2 were boiled with a reflux condenser in 10 ml of dry benzole for 4 h under magnetic stirring. The precipitate was filtered off, washed with dry sulphuric ether, and dried in a vacuum dessicator over Р 2 О 5 . The yield of product II was 0.55 g (88.71%), Т m = 185-187°C.

“…38 In continuation, condensation of [3-(triethoxysilyl)propyl]amine with 2-aminopyridine was carried out to synthesize 2-{ [3-(triethoxysilyl)propyl]amino}pyridine, which undergoes transesterification reaction to form 2-[(3-silatranylpropyl)amino]pyridine (42). 39 Several silatranes such as N-(1-methylsilatranyl)indole (43), N-(1-methylsilatranyl)pyrrole (44), N-(1-methylsilatranyl)carbazole (45) and 2-methyl-N-(1-silatranylmethyl)indole (46) were derived in the presence of potassium carbazolate and dibenzo-24-crown-8 in DMF. [40][41][42][43] Lower frequency shifts observed in IR spectra suggest increase in aromaticity of pyrrole ring in N-(1-methylsilatranyl)pyrrole.…”

Silatranes: a review on their synthesis, structure, reactivity and applications

2011

View full text Add to dashboard Cite

This critical review summarizes progress of the rapidly developing and very active field of silatrane chemistry. The first part of the review deals with general synthetic approaches used to synthesize different silatranes. The most interesting feature of silatranes, i.e., variation of Si-N bond length on the basis of the axial substituent of Si, and other structural features, are described in the second part with special emphasis on crystallographic and theoretical studies. It is followed by a discussion on the reactivity of various silatranes. Silatranes have now gained acceptance for a wide variety of applications which are summarized in the last section of review. Some of them have extensive interest due to their medical use to heal wounds or stimulate hair-growth (pilotropic activity), biological properties, pharmacological properties e.g. antitumor, anticancer, antibacterial, anti-inflammatory, fungicidal activity, stimulating effect in animal production and seed germination effects. The review focuses on the extended potential of silatranes in sol-gel processes, mesoporous zeotypes, atomic force microscopy, commercial products such as adhesion promoters, polymer formation and rubber compositions. This critical review will be helpful for general researchers, experts, advanced undergraduates and newcomers working on silatrane chemistry as this review presents greater emphasis on synthesis and characterization, structural properties, reactivity and applications of silatranes in the field of biology, material science, sol-gel chemistry, pharmaceutics, agriculture and medicine (311 references).
