  摘要：

  Spherical dendrimer of regular structure with the spatial characteristic S = 5, tetrakis[tris-(trimethylsilylethynyl)silyl-2-vinyldimethylsilylethynyl]silane, and the unsymmetrical binuclear dendrimer containing simultaneously groups (-CH(2)CH(2)-), (-CH=CH-), (-Ca parts per thousand C-) and combining the branches of the zero order (G0) and of the second generation (G2), 2-tris(trimethyl-silylethynyl)silyl-1-tris[tris(trimethylsilylethynyl)silylvinyldimethylsilylethynyl]silylethane were isolated from the reaction of hydrosilylation of tetrakis (dimethylethynylsilylethynyl)silane and vinyltris(dimethylethynylsilylethynyl)silane with trichlorosilane and a subsequent treatment of the reaction products with trimethylsilylethynylmagnesium bromide. NMR spectra of the synthesized compounds were studied.

  Synthesis of the mononuclear organosilicon tri- and tetradendrones of the first generation with the repeating C equivalent to C groups as well as the synthones for their construction is carried out. The tetrabranched polyunsaturated dendrimers GI having regular structure of containing silicon and germanium atoms simultameously are synthesized. The IR and NMR spectra of all the compounds obtained are studied, and molecular masses of the compounds are calculated and evaluated experimentally. Key parameters and chemical graphs of new dendrimers are presented.
