| Research Abstract |
It has been found in this study that, in the electroreductive intermolecular coupling of ketones with silyl substituted olefins, the existence of silyl group was found to play a important role for the regioselectivity and stereoselectivity of the reaction. This reaction is highly useful for the preparation of diols, formation of Si-Si bonds, and Si- carbon bonds. The elimination of Si atom in the coupling products was found to lead to the formation of the corresponding alcohols. This electroreductive method was also found to be useful for the reductive coupling of Si- and Ge-containing organic compounds. For examples, the electroreductive coupling of hydrosilanes led to the formation of new Si-Si and Si-C bonds with ordered sequences. The electroreduction of dichlorogerman gave poly- and oligo-germans, and poly silane-germans in good yields. By utilizing this method, the synthesis of optically active poly- and oligo-silanes has also been attained in this study.
