Arylamidate palladium complexes containing deprotonated phthalimide and p-methylbenzamide: possibility of their participation in reductive elimination
摘要:
Arylamidate palladium complexes containing deprotonated p-methylbenzamide and phthalimide have been synthesised; the latter has been characterised by X-ray diffraction data. A comparison of the catalytic and stoichiometric versions of N-arylation of p-methylbenzamide and phthalimide in the presence of palladium complexes and DPPF as a ligand has been carried out.

N-arylation of amides based on the formation of N-centered amidyl radicals via proton-coupled electron transfer (PCET) using a nickel–photoredox dual catalyst. The reaction achieved arylation of sterically hindered linear secondary amides under mild conditions. Control experiments with radical inhibitors suggested the formation of amidyl radicals via the PCET mechanism.
在此,我们报道了基于使用镍-光氧化还原双重催化剂通过质子耦合电子转移 (PCET) 形成 N 中心酰胺自由基的酰胺的 N-芳基化。该反应在温和条件下实现了空间受阻线性仲酰胺的芳基化。自由基抑制剂的对照实验表明,通过 PCET 机制形成酰胺自由基。
