An unsaturated α,ω-dianionic oligosilane

Abstract

A trisilenediide: The reduction of dichlorotrisilene 1 with active magnesium leads to α,ω-dianionic trisilene 2, which is characterized by NMR spectroscopy and X-ray diffraction. The potential of 2 as a precursor in the synthesis of heterocycles incorporating a Si=Si double bond is demonstrated by the formation of stannatrisilacyclobutene 3.
