Hexasilaprismanes synthesis

For the synthesis of hexasilaprismane, tetrachlorodisilane (RSiCl2—SiC R) and trichlorosilane (RSiCb) are utilized as the starting compounds. The Mg/MgBr2 reagent is quite useful also for the synthesis of hexasilaprismane. A hexasilaprismane derivative, hexakis(2,6-diisopropylphenyl)tetracyclo[2.2.0.02 6.03 5]hexasilane (12), was successfully... 

Recently, some attention has been focused on the synthesis and on the properties of strained cage compounds made up exclusively of Si atoms. As a consequence a number of derivatives of tetrasilatetrahedrane, hexasilaprismane and octasilacubane have been synthesized. The current knowledge in the field up to 1994 has been summarized...
