The first octasilacubane system: synthesis of octakis-(t-butyldimethylsilyl)pentacyclo[4.2.0.02,5.03,8.04,7]octasilane

Abstract

The first octasilacubane, octakis-(t-butyldimethylsilyl)pentacyclo[4.2.0.02,5.03,8.04,7]octasilane, was synthesised in one step by condensation of 2,2,3,3-tetrabromo-1,4-di-t-butyl-1,1,4,4-tetramethyltetrasilane or 1,1,1-tribromo-2-t-butyl-2,2-dimethyldisilane with sodium in toluene.
