A method was presented for the acylation of arenes using various aldehydesthrough dual CH activation at room temperature. The Pd-catalyst is initially activated to a triple state by absorbing energy from blue light. Furthermore, the 3Pd(AcO)2 required lower activation free energy to transition state 3(TS-2) based on the DFT calculation to ensure the reaction being proceeded at room temperature. This
提出了一种在室温下通过双 C H 活化使用各种醛进行芳烃酰化的方法。钯催化剂最初通过吸收蓝光能量被激活为三态。此外,根据DFT计算,3 Pd(AcO) 2需要较低的过渡态3(TS-2 )活化自由能,以确保反应在室温下进行。这种醛衍生的酰基自由基与钯催化的芳烃活化结合,产生交叉偶联产物。

A palladium-catalyzed ortho-acylation of N-benzyltriflamides from the alcohol oxidation level via C–H bondactivation is described. These transformations have been applied to a wide range of substrates, and typically proceed with excellent levels of chemoselectivity and with high functional group tolerance.
