In recent years, Dakin oxidation has evolved primarily around the conversion of ortho- and para-hydroxy benzaldehydes and acetophenones to dihydric phenols, which are found in nature and complex organic materials. In the traditional Dakin reaction, an excess amount of NaOH was used along with hydrogen peroxide. The synthetic community has devoted much time and effort to developing efficient basic, acidic and neutral reaction media for Dakin oxidation. The use of in situ generated H2O2 and molecular oxygen was also tested as an alternative oxidant for this reaction. In this review, we will discuss recent developments in Dakin oxidation with representative examples as well as future challenges and potential applications for this exciting field.

Dakin氧化法合成儿茶酚的新进展
近年来，Dakin 氧化主要围绕邻-和对-羟基苯甲醛和苯乙酮向二元酚的转化而发展，二元酚存在于自然界和复杂的有机材料中。在传统的 Dakin 反应中，过量的 NaOH 与过氧化氢一起使用。合成界投入了大量时间和精力来开发用于 Dakin 氧化的高效碱性、酸性和中性反应介质。使用原位生成的 H 2 O 2还测试了分子氧作为该反应的替代氧化剂。在这篇综述中，我们将通过代表性例子讨论 Dakin 氧化的最新发展，以及这个激动人心的领域的未来挑战和潜在应用。
