Conclusions
-
1.
The ethynyl-substituted dimethylfluoro-, methyldifluoro-, methylvinylfluoro-, and diethylfluorosilanes were synthesized for the first time by the reaction of ethynylalkoxysilanes with hydrofluoric acid, and also ethynyldimethylbromosilane from ethynyldimethylmethoxysilane and acetyl bromide.
-
2.
Some polysilylacetylenic compounds and alkylethynylallylsilanes were obtained from alkylethynylhalosilanes by the organomagnesium synthesis.
-
3.
Ethynyldimethylpiperidinosilane was obtained by the reaction of ethynyldimethylbromosilane with piperidine.
-
4.
trans-1-Dimethylfluorosilyl-2-trichlorosilylethylene was synthesized by the addition of trichlorosilane to ethynyldimethylfluorosilane.
