Swapped: Commercially available quinolinone derivatives (1 or 2, see scheme) were reacted with arylboronic acids in the presence of a RhI complex to give aryl(quinolin‐8‐yl)methanone products 3 in medium to good yields. A mechanism that involves the in situ oxidation of RhI to RhIII by O2 in the presence of CuI was proposed.
交换:在Rh I络合物存在下,将市售的喹啉酮衍生物(1或2,参见方案)与芳基硼酸反应,以中等至良好的收率得到芳基(quinolin-8-yl)methanone产品3 提出了一种机制,该机制涉及在CuI存在下用O 2将Rh I原位氧化为Rh III。
