Tailor-made synthesis of functional substituted oligosilanes from silyl triflates and (aminosilyl)lithium compounds

Diethylamino substituted silyllithium compounds have been prepared in situ from the corresponding phenylchlorosilanes and lithium. These reagents undergo coupling reactions with triflate derivatives of silanes and oligosilanes. Exchange processes analogou

Mixed reagent (aminosilyl)lithium/i-PrMgBr for the synthesis of functionalized oligosilanes

Mixed reagents prepared in situ from the (aminosilyl)lithiums with i-PrMgBr undergo coupling reactions with chloro-oligosilanes without Si-Si bond cleavage, which is a serious side reaction with the (aminosilyl)lithiums themselves. Based on the coupling reaction and the amino-to-chloro transformation, functionalized tetrasilanes and hexasilanes are synthesized. The analysis of the 1H- and 29Si-NMR spectra indicates that these oligosilanes include three configurational isomers, ll, ul, and uu.
