The first nickel‐catalyzed N‐arylation of amides with (hetero)aryl (pseudo)halides is reported, enabled by use of the air‐stable pre‐catalyst (PAd‐DalPhos)Ni(o‐tolyl)Cl (C1). A range of structurally diverse primary amides and lactams were cross‐coupled successfully with activated (hetero)aryl chloride, bromide, triflate, tosylate, mesylate, and sulfamate electrophiles.
据报道,使用空气稳定的预催化剂(PAd-DalPhos)Ni(o -tolyl )Cl(C1)可以使酰胺与(杂)芳基(假)卤化物进行第一个镍催化的N-芳基化反应。一系列结构多样的伯酰胺和内酰胺已与活化的(杂)芳基氯,溴化物,三氟甲磺酸盐,甲苯磺酸盐,甲磺酸盐和氨基磺酸亲电子试剂成功交叉偶联。
