摘要：

The synthesis of the precursor phenylthiomethyl-functionalized carbosilane dendrimers Si[(CH2)(3)SiMe2CH2SPh](4) (1) and Si{(CH2)(3)Si[(CH2)(3)SiMe2CH2SPh](3)}(4) (2) is described. Reacting 1 and 2 with lithium naphthalenide gives the first lithiomethyl-functionalized dendrimers Si[(CH2)(3)SiMe2CH2Li](4) (7) and Si[(CH2)(3)Si[(CH2)(3)SiMe2CH2Li](3)}(4) (11). Deutero, trimethylsilyl, trimethylstannyl, and tri-n-butylstannyl derivatives of these dendrimers, as well as a method to enable isolation of the lithiated dendrimers as solids, are described.
