An unexpected Cu-catalyzed deoxygenative C2-sulfonylation reaction of quinoline N-oxides in the presence of radical initiator K2S2O8 was developed that used sodium sulfinate as a sulfonyl coupling partner. The mechanism studies indicate that the reaction proceeds via Minisci-like radical coupling step to give sulfonylated quinoline with good chemical yields.
在自由基引发剂K 2 S 2 O 8的存在下,开发了出乎意料的Cu催化的喹啉N-氧化物的C2-磺酰化脱氧反应,该反应使用亚磺酸钠作为磺酰基偶联剂。机理研究表明,该反应通过类似Minisci的自由基偶联步骤进行,从而得到具有良好化学收率的磺酰化喹啉。
