regioselective ortho‐benzoxylation of N‐alkyl benzamides with aromatic acids in the presence of [RuCl2(p‐cymene)}2], AgSbF6, and (NH4)2S2O8 in 1,2‐dichloroethane at 100 °C for 24 h affording ortho‐benzoxylated N‐alkyl benzamides by CH bond activation is described. Further, Ru‐catalyzed alkenylation is done at the ortho CH bond of benzoxylated N‐alkyl benzamides with alkenes in water solvent. Subsequently
在[RuCl 2(p- cymene)} 2 ],AgSbF 6和(NH 4)2 S 2 O 8在1,2-二氯乙烷中存在下,N-烷基苯甲酰胺与芳香酸的高度区域选择性邻苯甲酰化在100℃下24小时,得到邻-benzoxylated ñ -烷基苯甲酰胺用C H键活化进行说明。此外,钌催化的烯基是在完成邻Ç 的benzoxylated H键Ñ烷基苯甲酰胺与烯烃在水的溶剂中。随后,在碱或酸的存在下,N-烷基苯甲酰胺的苯甲酰基部分转化为羟基。提出了可能的反应机理来解释当前的偶联反应。
