method that involves the generation of a “cation pool” using low-temperature electrolysis, and then its reaction with nucleophiles under non-oxidative conditions. This one-pot method solves problems associated with conventional oxidative generation of cations and their in situ reaction with nucleophiles, and provides an efficient method for direct oxidative carbon−carbon bond formation. As an example
我们开发了一种方法,该方法涉及使用低温电解产生“阳离子池”,然后在非氧化条件下与亲核试剂反应。这种一锅法解决了与阳离子的常规氧化生成及其与亲核试剂的原位反应相关的问题,并提供了一种直接氧化碳-碳键形成的有效方法。作为该方法的一个例子,研究了通过低温电解 (-72 °C) 从氨基甲酸酯生成阳离子池及其与碳亲核试剂如烯丙基硅烷、烯醇甲硅烷基醚和烯醇乙酸酯的反应,并在良好的收益。芳香族化合物和 1,3-二羰基化合物也可用作碳亲核试剂。
