Outline of Final Research Achievements

We have designed and developed the new type of divided cell, in which three-way cock was incorporated in the center position of the cell, which enables
the electrolyzed cathodic solution to transfer into anodic chamber by using the balloon after the electrolysis. As the examples of the successful results, the electrolysis of enol silyl ether in the anode and PhSH in the cathode and the solution transfer gave the corresponding the PhS-contained product, despite of the low yields. The paired electrolysis of in-situ generated iminium cation and allylsilanes and the solution transfer gave the products of C-C bond formations. Besides, various successful results containing the electro- and non-electro- synthesis were obtained for 3 years.

Academic Significance and Societal Importance of the Research Achievements

電気エネルギーそのものを試薬とする有機電解合成は、近年、環境調和型手法として世界的な注目を集めている。しかしながら分離型電解セルを用いた両極合成とその陽極、陰極溶液を用いた分子変換は、電解後の両方の溶液の混合がネックとなり、開発が遅れていた。本研究では、研究代表者がオリジナルな電解セルを開発して、従来開発されていなかった分子変換の検討を行った。合成した化合物のいくつかは、医薬品、薬理活性分子にも含まれる基本骨格であるので、基礎研究として社会的な意義は深いと考えている。
