“…N-(1-Silatranylmethyl)-substituted nitrogen heterocycles (58 and 59) can be synthesized from their precursors very efficiently. 49,50 Along with the influence of the electron withdrawing effect of heterocyclic substituent on the 29 Si NMR signal, a significant influence of silatranylmethyl moiety was observed on the 15 N NMR signal which displayed a variation of 0.6-20 ppm from analogous 1-methylazoles. A characteristic shielding of 29 Si and deshielding of 15 N was observed with the increase in electron withdrawing effect of heterocyclic substituent.…”

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).

“…Route 1 was also utilized for synthesizing previously unknown derivatives of S-(silatranylmethyl)isothiuronium halides (49)(50)(51)(52)(53)(54)(55). 47 During the course of reaction, the corresponding tris(2-hydroxyethyl)ammonium halides were also isolated as side products.…”

“…Phthalimide derivatives are the most searched class of heterocyclic compounds due to their enormous biological applications such as anti-inflammatory, hypolipidemic, anti-cancer, anti-HIV and analgesic agents etc. [8][9][10]. These are used in organic and drug synthesis exhibiting pharmaceutical activities as anticholinergic and anti-Parkinsonian agent [11].…”
