…They introduced carboxyl groups to a graphite electrode by air oxidation at 160°C, then converted it to an acid chloride with thionyl chloride SOCl 2 , and used ( S )-phenylalanine methyl ester to create an electrode with phenylalanine amide bond (see figure), which was used for the asymmetric reduction of 4-acetylpyridine and ethyl phenylglyoxylate. For metal and metal oxide electrodes, functional groups are introduced by utilizing the hydroxyl groups on the surface.

…彼らはグラファイト電極を160℃で空気酸化してカルボキシル基を導入した後,塩化チオニルSOCl2で酸クロリドとなし,(S)‐フェニルアラニンメチルエステルを用いてフェニルアラニンをアミド結合した電極を作成し(図参照),この電極を用いて4‐アセチルピリジンおよびフェニルグリオキシル酸エチルを不斉還元した。金属電極や金属酸化物電極では,表面のヒドロキシル基を利用して官能基を導入する。【笛木 和雄】。… ※「金属酸化物電極」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
