摘要

当需要利用α位置羰基衍生物的酸性形成CC键时，使用烯醇酯化学是一种选择。然而，一种相反极性的烯醇酸化学正在出现，利用亲电自由基在相同的α位置上具有一个自由基位点代替负电荷。可见光光氧化还原催化正在成为生成这些自由基的理想工具，从而使它们在几种合成路线中得到广泛应用。本综述的目的是收集最近的例子，光产生的亲电自由基的化学锻造新的CC或其他CY键。

Photogenerated electrophilic radicals for the umpolung of enolate chemistry

The use of enolate chemistry is the election choice when a CC bond formation is required exploiting the acidity of carbonyl derivatives in the α position. However, a reversed-polarity equivalent of enolate chemistry is emerging making use of electrophilic radicals having a radical site in place of a negative charge in the same α position. Visible light photoredox catalysis is becoming the ideal tool for the generation of these radicals thus allowing their wide application in several synthetic routes. Aim of this review is to collect recent examples of the chemistry of photogenerated electrophilic radicals for the forging of new CC or other CY bonds.
