An efficient visible-light-induced CH arylation of quinoxalin-2(1H)-ones in H2O is developed, which has the advantages of mild reaction conditions, environmental friendliness and good functional group tolerance. This strategy provides a simple operation method to access various 3-aryl quinoxalin-2(1H)-ones in moderate to good yields.
Two facile and effective C-3 arylation protocols of quinoxalin-2(1H)-ones with arylhydrazines and aryl boronic acids respectively via free radical cross-coupling reactions under metal-, photocatalyst- and light-free conditions have been unveiled. K2S2O8 has been used as an efficient oxidant to generate aryl radicals from arylhydrazines and aryl boronic acids under two different reaction conditions
已经揭示了喹喔啉-2( 1H )-酮分别与芳基肼和芳基硼酸通过自由基交叉偶联反应在金属、光催化剂和无光条件下进行的两种简便有效的C-3芳基化方案。 K 2 S 2 O 8已被用作有效的氧化剂,在两种不同的反应条件下由芳基肼和芳基硼酸生成芳基自由基。生成的芳基自由基在喹喔啉-2(1 H )-酮的C-3位发生自由基偶联反应,以良好至优异的产率产生3-芳基喹喔啉-2(1 H )-酮。 2,2,6,6-四甲基哌啶-1-氧基自由基捕获实验已证明自由基参与反应过程。

An effective and practical methodology for the desulfitative coupling of quinoxalin-2(1H)-ones with arylsulfonyl chlorides under palladium catalysis is presented. This protocol leads to the formation of carbon–carbon bond and provides a straightforward pathway to access C3-arylquinoxalin-2(1H)-ones.
提出了一种在钯催化下将喹喔啉-2(1 H )-酮与芳基磺酰氯脱硫偶联的有效实用方法。该协议导致碳-碳键的形成,并提供了一条直接的途径来获得 C3-arylquinoxalin-2(1 H )-ones。
