An efficient C-H acylation of azo- and azoxybenzenes with α-keto acids has been developed by a combination of palladium catalysis and visible-light photoredox catalysis at room temperature under 1.5 W blue LED irradiation. This method tolerates a variety of disubstituted azo- and azoxybenzenes, as well as α-keto acids regardless of the nature of the substituents. A number of aryl ketones were obtained in good yields under mild reaction conditions.
通过钯催化和可见光光氧化还原催化相结合，在室温下1.5瓦蓝色发光二极管照射下，开发了一种有效的偶氮苯和氧化偶氮苯与α-酮酸的C-H酰化反应。该方法适用于各种二取代偶氮苯和氧化偶氮苯，以及α-酮酸，无论取代基的性质如何。在温和的反应条件下，以良好的产率得到了多种芳基酮。
