processes afford the α,δ-dicarboxylated product, the selective mono-carboxylation of dienes is a significant challenge and the major product reported under transition metal catalysis arises from carboxylation at the α-carbon. Herein we report a new electrosynthetic approach, that does not rely on a sacrificial electrode, the reported method allows unprecedented direct access to carboxylic acids derived from
迄今为止,大多数二烯羧化过程提供了α,δ-二羧化产物,二烯的选择性单羧化是一个重大挑战,过渡金属催化下报道的主要产物是由α-碳的羧化产生的。在本文中,我们报告了一种不依赖牺牲电极的新的电合成方法,该报告的方法允许空前直接访问δ位置二烯衍生的羧酸。另外,通过简单地改变反应条件,可以容易地获得α,δ-二羧酸或α,δ还原的烯烃。
