Reductive Oligomerization of 1,2‐Di‐<i>tert</i>‐butyl‐1,1,2,2‐tetrachlorodisilane: The Tricyclo[2.2.0.0^2,5]hexasilane and Tetracyclo[3.3.0.0^2,7.0^3,6]octasilane Systems

Abstract

Highly strained polycyclic silanes such as the tetracyclooctasilane derivative 1 were obtained in a unique and somewhat unexpected way. Besides 1, mono- and tricyclic compounds were formed, but no compounds with cubane or prismane skeleton. To all appearances the carbon analogue of 1 still does not exist.
