Cross-electrophile coupling reactions of different electrophiles have been extensively studied but mainly limited to bromides and iodides. Here, we report an electrochemically induced nickel-catalyzed cross-electrophile coupling strategy between alkenyl triflates and α-chloroamides in an undivided cell under mild reaction conditions, affording the α-functionalized amide derivatives in good to excellent yields with broad substrate scopes and good functional group tolerance. The control experiments were conducted, and a plausible mechanism was proposed.
不同亲电试剂的交叉亲电偶联反应已得到广泛研究,但主要限于溴化物和碘化物。在此,我们报道了一种电化学诱导的镍催化的烯基三氟甲磺酸酯与α-氯代酰胺之间的交叉亲电偶联策略,该反应在温和的反应条件下于未分隔的电池中进行,以良好至优异的产率提供α-官能化酰胺衍生物,底物范围广泛且官能团耐受性良好。进行了对照实验,并提出了一种合理的机理。
