confinement: Lewis acid catalyzed reactions have been conducted on arrays with either 1024 or 12 544 microelectrodes cm−2. A ScIII species generated at the electrodes is employed as the Lewis acid, and the reagent is confined to the electrodes through the use of a solution‐phase reductant. A multicomponent synthesis of a tetrahydropyran (see scheme), a Diels–Alder reaction, and an esterification reaction are
试剂限制:在具有1024或12 544个微电极cm -2的阵列上进行了路易斯酸催化的反应。电极上产生的Sc III物质用作路易斯酸,并且通过使用溶液相还原剂将试剂限制在电极上。四氢吡喃的多组分合成(参见方案),Diels-Alder反应和酯化反应均与此策略兼容。
