Fluorosulfonyl-containing heterocyclic compounds

Hexafluoroisobutenylidene sulfate is a sulfotrioxidizing agent with respect to various olefins; methylenemethionic acid is formed in the case of ethylene, while the corresponding-sulfones are formed in the case of tetrafluoroethylene and vinylidene fluoride. 2,2-Difluoro-2-hydroxy-ethanesulfonic acid sultone is characterized by a capacity for anionotropic transformations; a number of sulfoacetic acid derivatives were obtained on the basis of this sultone.See [1] for communication III.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 178–182, February, 1973.     

Stabilization of reaction products of ureas with polyfluoro ketones

Conclusions Polyfluorinated tetrahydro-1,3,5-oxadiazine derivatives were obtained by the condensation of urea and thiourea with polyfluoro ketones.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2168–2169, September, 1977.     

Ionotropic reactions of β-sultones

The reaction mechanism of-sultones are discussed; a scheme for the reactivity is proposed. Polyfluoro--sultones can undergo anionotropic reactions of the type Hydrogeneous-sultones under prototropic reactions:     

Reaction of bis(triethylgermyl)mercury with mercurated acid nitriles

Conclusions The exchange reaction of the radicals between bis(triethylgermyl)mercury and mercury derivatives R₂Hg (R=C(Me₂)CN, C(CF₃)₂CN, CH(CN)₂) leads to the formation of unstable Et₃GeHgR compounds. The composition of the decomposition products of these compounds depends on the nature of R.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2800–2802, December, 1977.
