  Spherical polyunsaturated organosilicon and organogermanium first generation dendrimers of regular structure

  摘要：

  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.

  The known tetrakis((trimethylsilyl)ethynyl)silane was prepared and deprotected. By using trifluoromethanesulfonic acid, the smooth stepwise desilylation of the starting material was achieved, and all of the partially protected and the fully deprotected species were isolated by sublimation. Crystal structures of all of the partially and the fully deprotected species were obtained. None of the compounds
