Abstract

The synthesis of the precursor phenylthiomethyl-functionalized carbosilane dendrimers Si[(CH₂)₃SiMe₂CH₂SPh]₄ (1) and Si{(CH₂)₃Si[(CH₂)₃SiMe₂ CH₂SPh]₃}₄ (2) is described. Reacting 1 and 2 with lithium naphthalenide gives the first lithiomethyl-functionalized dendrimers Si[(CH₂)₃SiMe₂CH₂Li]₄ (7) and Si{(CH₂)₃Si[(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.
