palladium(II)‐catalyzed biomimetic aliphatic acyl (‐COR) group transfer was observed from acyl‐α‐peroxycoumarins to the ortho CH sites of directing arenes. Here, the CH activation is associated with a concomitant acyl group transfer via a Pd(II)‐catalyzed, redox‐neutral process. While methods for ortho aroylation (‐COAr) are well documented ortho acylation (‐COR) processes are scarce, hence the present
由酰基α-peroxycoumarins观察到前所未有的钯(II) -催化的仿生脂族酰基(-COR)基团转移邻Ç 引导芳烃h的位点。在这里,CH活化与经由Pd(II)催化的氧化还原中性过程的伴生酰基转移相关。尽管有充分文献证明邻芳基化(‐COAr)方法很少进行邻酰化(‐COR)工艺,因此,目前的氧化还原中性方法最适合直接对底物进行o酰化。
