A Pd(II)-catalyzed straightforward oxidative naphthylation of unmasked 2-pyridone derivatives is described using a twofold internal alkyne as a coupling partner. The reaction proceeds through N–H/C–H activation to provide polyarylated N-naphthyl 2-pyridones. An unusual oxidative annulation at the arene C–H bond of the diarylalkyne leads to the formation of polyarylated N-naphthyl 2-pyridones, where
使用双重内部炔烃作为偶联伙伴描述了 Pd(II) 催化的未掩蔽 2-吡啶酮衍生物的直接氧化萘基化。该反应通过 N-H/C-H 活化进行,以提供多芳基化的N-萘基 2-吡啶酮。在二芳基炔烃的芳烃 C-H 键处发生不寻常的氧化环化导致多芳基化N-萘基 2-吡啶酮的形成,其中萘环的 2-吡啶酮连接的苯环被多芳基取代。机理研究和 DFT 计算提出了一种基于 N-H/C-H 活化的合理机制。研究了N-萘基 2-吡啶酮衍生物以探索令人鼓舞的光物理特性。
