Rearrangement of radicals during telomerization of ethylene with ethanol

Conclusions Rearrangement of the radicals, with a 1,5-migration of the hydrogen atom, occurs during the telomerization of ethylene with ethanol.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2593–2594, November, 1972.     

Radical telomerization of ethylene by diethyl carbonate

Conclusions The telomerization of ethylene by diethyl carbonate leads to the formation of a single series of telomers with structure EtOC(O)OCH(Me)(CH₂CH₂)_nH.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1890–1892, August, 1984.     

Reaction of silicon hydrides with primary aliphatic amines

Conclusions The direction of the reaction of the silicon hydrides: R₂SiH₂, RSiH₃, and with primary aliphatic amines, in the presence of catalysts based on Group VIII compounds, as a function of the structure of the silicon hydride and the nature of the employed catalyst, was established.Deceased.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2330–2333, October, 1972.     

Complexes of N-derivatives of silicon hydrides with aluminum chloride

Conclusions A study was made of the reaction of the N-derivatives of silicon hydrides with aluminum chloride, and it was shown that aluminum-containing organosilicon complexes can be obtained from them.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2149–2150, September, 1973.     

Chain transfer constants in the telomerization of ethylene by methyltrichloroacetate

Conclusions The chain transfer constants in the telomerization of ethylene by methyltrichloroacetate were measured. A monotonic increase in the constants from C₁ to C₄ is observed at constant temperature. In the temperature interval 55–120°, the chain transfer constants vary little with the temperature.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 73–77, January, 1971.     

Chain transfer mechanism and kinetics in radical telomerization of ethylene with bromalkanes

Rate constants for chain transfer via bromoalkanes of various structure are estimated for primary, secondary and tertiary alkyl radicals and isokinetic dependences are shown to exist for their activation parameters. Isokinetic temperatures are calculated.

Reactions of trimethylgallium with silicon hydrides,germane and diborane

Methylation of SiH₄, MeSiH₃, Si₂H₆, GeH₄ and B₂H₆, but not of PH₃ or AsH₃, was observed during reaction (230–324°C) with GaMe₃. The products from the SiH₄ and Si₂H₆ reactions were MeSiH₃, Me₂SiH₂ and Me₃SiH. The GeH₄-derived products were similar, with Me₄Ge also being formed. The only methylated products from B₂H₆ was BMe₃. The silane reactions were surface-catalyzed (presumably by surface hydroxyl groups), while those of GeH₄ and B₂H₆ may have occurred via gas-phase free radical processes.
