Abstract: | Spherical dendrimer of regular structure with the spatial characteristic S = 5, tetrakistris-(trimethylsilylethynyl)silyl-2-vinyldimethylsilylethynyl]silane, and the unsymmetrical binuclear dendrimer
containing simultaneously groups (−CH2CH2−), (−CH=CH−), (−C≡C−) and combining the branches of the zero order (G0) and of the second generation (G2), 2-tris(trimethyl-silylethynyl)silyl-1-tristris(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. |
