Outline of Final Research Achievements

Hexasilabenzene is the silicon analog of benzene. In contrast with benzene, the energy of hexasilabenzene is by 36.0 kcal mol-1 higher than the most stable valence isomer, and therefore, hexasilabenzene has not yet been synthesized. According to theoretical calculations, hexasilabenzene with three 1,4-cyclohexasilanylene groups is estimated to be the most stable among its valence isomers. In this research, synthesis of hexasilabenzene with 1,4-cyclohexasilanylene groups was studied.
