The first nickel-catalyzed cross-coupling reactions between fluoroarenes and aryl organometallics using commercially available ligands are described. The nickel-catalyzed cross-coupling reactions between aryl Grignard reagents and fluoroazines and -diazines occurred in THF at room temperature using commercially available 1,2-bis(diphenylphosphino)ethane, 1,3-bis(diphenylphosphino)propane, or 1,1'-
描述了使用商业上可获得的配体在氟代芳烃和芳基有机金属化合物之间的第一镍催化的交叉偶联反应。使用市售的1,2-双(二苯基膦基)乙烷,1,3-双(二苯基膦基)丙烷或1,1在室温下于THF中在芳基格氏试剂与氟嗪和-二嗪之间进行镍催化的交叉偶联反应。 '-双(二苯基膦基)二茂铁作为配体。各种氟底物(例如吡啶,二嗪(吡嗪,哒嗪),苯并二嗪(喹喔啉)和喹啉)已成功地与苯基卤化镁(苯基氯化镁,2-甲氧基苯基溴化镁和4-甲氧基苯基溴化镁)反应。所使用的条件还允许4-氟甲苯与芳基镁试剂的交叉偶联。
