Abstract

2,2,3,3,5,5,6,6,7,7,8,8-Dodecamethyl-2,3,5,6,7,8-hexasilabicyclo[2.2.2] octane (1) was synthesized for the first time via three steps in 56% overall yield through triple silylation with three dichlorodimethyldisilane molecules of two trianionic molecules derived from bis(phenylthio)methane. The molecular structure of 1 was shown to be slightly distorted from an ideal bicyclo-[2.2.2]octane skeleton by X-ray analysis. The derivatization of 1 and UV spectra of those compounds are described.
