Abstract
Mixed reagents prepared in situ from the (aminosilyl)lithiums with i-PrMgBr undergo coupling reactions with chloro-oligosilanes without Si-Si bond cle avage, which is a serious side reaction with the (aminosilyl)lithiums thems elves. Based on the coupling reaction and the amino-to-chloro transformatio n, functionalized tetrasilanes and hexasilanes are synthesized. The analysi s of the H-1- and Si-29-NMR spectra indicates that these oligosilanes inclu de three configurational isomers, ll, ul, and uu. (C) 2000 Elsevier Science S.A. All rights reserved.
