A direct route to a novel tetraphenyldisilabicyclo[2.2.2.]octa-2,5-diene: a tetraphenyldisilene precursor
Abstract
Synthesis of 2:3,5:6-dibenzo-7,7,8,8-tetraphenyl-7,8-disilabicyclo[2.2.2.]octa-2,5-diene from di-chlorodiphenylsilane, anthracene and magnesium-magnesium bromide in THF is described; the disilabicyclo compounds was found to undergo a retrodiene reaction, affording anthracene and presumably tetraphenyldisilene.
