Workup of the mixture of products of pyrolysis of cyclotetrasiloxane (Me2SiO)2(MePhSiO)2 yielded 1,3- (I) and 1,5-(o-phenylene)cyclosiloxane (II), the structures of which were established on the basis of data from their IR, PMR, and mass spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 24–25, January, 1978. 相似文献

Gas phase reaction of dichlorogermylenes formed in the systems GeCl4-Si2Cl6 or Ge-GeCl4 with 1,2-dichloroethylene and trichloroethylene was studied. It is shown that:GeCl2 inserts into the C-Cl bond of 1,2-dichloroethylene and forms the derivatives with one or two trichlorogermyl groups. A specific feature of the reaction of:GeCl2 with trichloroethylene was found. In this reaction the formation of only monosubstituted compounds like 1,1-dichloro-2-trichlorogermylethylene and 1,2-dichloro-1-trichlorogermylethylene takes place. The rule established is valid in general also for the reaction of trichloroethylene with dichlorosilylene, another analog of carbene. Reactions taking place in the course of synthesis of organochlorogermanes are considered. 相似文献

The results of studies carried out in the past five years on the gas-phase synthesis of organochlorosilanes, pentachlorodisiloxanes,
organochlorogermanes, and organochlorostannanes at 400–550 °C in the presence of hexachlorodisilane or 1,1-dichloro-1-silacyclopent-3-ene
as sources of dichlorosilylene are summarized.
Dedicated to the memory of Academician M. E. Vol'pin timed to his 75th birthday.

1. | Differences have been shown in the mass spectra of isomeric 1,1-difluoro- and 1,1-dichloro-1-silacyclopentenes, and also 1,1-dichloro-, 1,1-dihydro-, and 1,1-dideuterio-1-silacyclohexadienes, differences that make it possible to identify the isomers. |
2. | Mass spectrometry has been used to identify the intermediates formed in the vacuum pyrolysis of these silicon-containing cyclic compounds, and it has been established that all of the dihalo derivatives dissociate selectively, splitting off the corresponding dihalosilylene. |
3. | In the thermal dissociation of sila-2,5-cyclohexadiene, hydrogen splits off selectively from the silicon atom and one of the carbon atoms, forming silabenzene — a molecule with a multiple carbon-silicon bond. The mass spectrum of silabenzene has been obtained for the first time. |
