Abstract
Abstract Hexakis(trimethylsilyl)disilane (1), a novel, highly branched and symmetrical polysilane, was synthesized by a number of procedures. Many of these gave (I) in only 5–9% yield. The reaction of tris(trimethylsilyl)silyllithium (II) with 1,2-dibromoethane ( ca .-70°) gave (I) in 45–50% yields, and proved to be the most satisfactory method of synthesis. The physical and spectral properties of (I) are discussed. Lithium and methyllithium reacted with (I) to cause cleavage of the symmetrical Si Si bond, while (II), triphenylsilyllithium and halogens effected cleavage of peripheral trimethylsilyl groups.
