A highly regioselective ortho arylation of N-(2-benzoylphenyl)benzamides has been achieved with aryl iodides in the presence of 10 mol% Pd(OAc)2 and a stoichiometric amount of AgOAc under solvent-free conditions via C-H activation to produce the corresponding 2-arylated benzamides in good yields.
在无溶剂条件下,在 10 mol% Pd(OAc)2 和
化学计量的 AgOAc 存在下,通过 C-H 活化,用芳基
碘化物实现了 N-(2-苯甲酰苯基)苯甲酰胺的高度区域选择性邻位芳基化,生成相应的2-芳基化苯甲酰胺的收率良好。
