摘要：
The invention provides a novel organosilicon compound poly(dimethylsilmethylene) methylacetylene compound of the formula MeC.tbd.C--SiMe.sub.2 --CH.sub.2 --SiMe.sub.2).sub.n Me, in which Me is a methyl group and n is a positive integer of 1 to 25. The compound is synthesized by reacting a propynylmagnesium halide of the formula MeC.tbd.CMgX, in which X is a halogen atom, or (propynyl dimethylsilyl)methylmagnesium chloride of the formula MeC.tbd.C--SiMe.sub.2 --CH.sub.2 MgCl with chloromethyl dimethyl chlorosilane in the presence of metallic magnesium and hydrolyzing the reaction product. Specifically, 1-propynyl-1,1,3,3,3-pentamethyl disilmethylene, i.e. the inventive compound with n=1, is synthesized by reacting (propynyl dimethylsilyl)methylmagnesium chloride with trimethyl chlorosilane.
