1-Halosilatranes

Chemistry of heterocyclic compounds at the A. E. Favorsky Irkutsk Institute of Chemistry, Siberian Branch of the Russian Academy of Sciences, over 50 years (Review)

“…As a result of fundamental investigations by M. G. Voronkov's school in the chemistry, physical chemistry, biology, and pharmacology of silatranes (chelated tricyclic silicon ethers of triethanolamine) and also other compounds of hypervalent silicon, silicon has become the basis of a new branch of science -bio-silicon organic chemistry [361][362][363][364][365][366][367][368][369]. During this period hundreds of silatranes have been synthesized and investigated, and new theoretical data initiating vigorous development in the chemistry of hypervalent silicon were obtained [64,308,365,[369][370][371][372].…”

“…During this period hundreds of silatranes have been synthesized and investigated, and new theoretical data initiating vigorous development in the chemistry of hypervalent silicon were obtained [64,308,365,[369][370][371][372]. The wide variety of methods used for the production of silatranes [64,[361][362][363][364] is represented in general form in the following scheme. Numerous derivatives and analogs of silatranes have been synthesized [364,273].…”

Silatranes and Their Tricyclic Analogs

“…The use of iodo derivatives CH 2 I 2 or CHI 3 in reaction 66 results only in polymeric products 308 Both 49 and trialkylsilanes undergo exchange reactions with trimethylhalosilanes in the presence of quinoline to give 1-halosilatranes (equation 73) 16 . It is likely that steric hindrance is responsible for the lack of addition of 1-hydrosilatrane (49) to the multiple bond of monosubstituted alkenes and acetylenes in the presence of H 2 PtCl 6 or under UV irradiation 129,310 .…”

Reactions of 1-hydro-and 1-halosilatranes with metal salts

“…11 Redox reactions with compound 1 as a reducing agent remain poorly investigated. The results we presented here can be used to develop new methods for the synthesis of silatranes and obtain further data on the structure of the silatranyl cation.…”
