Unsymmetrical 1,2-bis(diorganylsilyl)ethanes were synthesized by two procedures. Hydrosilylation of chloro(vinyl)silanes were used to obtain compounds of the general formula ClMe2SiCH2CH 2SiRMeCl with different substituents (R = Et, Vin, Ph) on the silicon atom. Chlorodealkylation of 1,2-bis(trialkylsilyl)ethanes gave compounds of the general formula ClAlk2SiCH2CH2SiAlk 2Cl (Alk = Me, Et, Pr). It is established that the latter reaction provides high yields only with Me-and Et-substituted compounds, whereas Pr-substituted products are formed in poor yields. The mechamism of this reaction based on quantum-chemical calculations is offered.
Organosilicon compound and process for producing organosilicon compound

, (2008/06/13)
An organosilicon compound having a Si--C--C--Si bond, a C=C--Si bond and/or a CH--CH--Si bond is prepared by reacting an olefin or a substituted olefin with a disilane in the presence of a platinum-containing catalyst. The resulting compound can be further treated with an alkyl lithium, an aryl lithium or a Grignard reagent.
