Carboxylate anions, dianions and ester enolates provide simultaneous protection and activation for directed carbometalation reactions. Advantage can be taken of the bis‐carbanionic character of the intermediate for further controlled CC bond forming reactions.
羧酸根阴离子,二价阴离子和酯烯醇盐可为定向的碳金属化反应提供同时的保护和活化。可以利用中间体的双碳负离子特性进一步控制CC键形成反应。
