Summary
-
1.
The dehydrochlorination of the following compounds was carried out for the first times With the aid of quinolines Cl2SiCH2CHClCH2, Cl2SiCH2CCl(CH2)2 and Cl2SiCHClCH2SiCl2. With the aid of aluminum chloride: 1,1- 1,2- and 2,2-dichloroethyltrichlorosilanes, Cl2SiCH2CH (CH2)CH2Cl and Cl2SiCHClCH2SiCl2.

2.
It was shown that, when quinolines was used, dehydrochlorination products were obtained in high yield only when the chlorine atom was in the\gb-position with respect to silicon, the products being exclusively 1-alkenylsilanes. Aluminum chloride can be applied for dehydrochlorination only in the case of trichlorochloroalkyl)silanes, but the chlorine atom may be in the\ga-,\gb-, or\gg-position.

3.
A new arrangement in organosilicon chemistry was discovered.
In the dehydrochlorination of 1-chloro-1,2-bistrichlorosillylethane (1,1,2,4,4,4-heptachloro-1,4-disilabutane) with quinoline, only 1,2-bistrichlorosilylethylene was formed, whereas in dehydrochlorination with aluminum chloride the same product was obtained in admixture with 1,1-bistrichlorosilylethylene. A scheme is given in which an isomeric change in the skeleton of the original compound occurs in the course of the dehydrochlorination.
