  Preparation of dendritic carbosilanes containing ethynyl groups and dicobalt hexacarbonyl clusters on the periphery

  摘要：

  Dendritic carbosilanes have been prepared by the use of 2,4,6,8-tetramethyl-2,4,6,8-tetravinyl-2,4,6,8-tetrasila-1,3,5,7-tetraoxacyclooctane (CH2=CHMeSiO), and 1,2-bis(triallylsilyl)ethane ((CH2=CHCH2)(3)SiCH2)(2) as core molecules, diallylmethylsilyl groups ((CH2=CHCH2)(2)MeSi-) as building blocks and bisphenylethynylmethylsilyl groups ((PhC=C)(2)MeSi-) as terminating groups. The phenylethynyl-group-containing terminal generation is produced by the reaction of the chlorosilylated generation with lithium phenylacethylide. The reaction of dicobalt octacarbonyl Co,(CO), with phenylethynyl groups gave the corresponding phenylethynyl hexacarbonyl complexes (2Co(2)(CO)(6).(PhC=C)(2)MeSi-dendimer) on the periphery. The yields of the prepared dendrimers with phenylethynyl terminal groups and their cobalt carbonyl complexes are obtained nearly quantitatively. They are characterized by the use of spectroscopic analyses (H-1-, and C-13-NMR, UV and IR) as well as MALDI mass spectroscopy and elemental analysis. (C) 1999 Elsevier Science S.A.

  Dendritic carbosilanes with hydroxy groups on the periphery have been prepared. The hydroxy-group-containing dendrimers were prepared by the use of the hydroboration of carbosilane dendrimers containing double bonds with 9-BBN and the subsequent oxidation of the prepared dendrimers. Oxidation of the hydroborated dendrimers in an alkali medium gave quantitative yields. The hydroboration and oxidation

  已经制备了在外围具有羟基的树枝状碳硅烷。通过使用含有与9-BBN的双键的碳硅烷树状聚合物的硼氢化和随后氧化所制备的树状聚合物来制备含羟基的树状聚合物。在碱性介质中氧化硼氢化的树枝状大分子得到定量的产率。通过1 H-和13 C-NMR光谱监测硼氢化和氧化过程。使用MALDI质谱法，在所有情况下，均已对具有羟基的碳硅烷树状大分子的统一形式进行了表征。
