couple: Cooperative bimetallic activation of CF and CO bonds gave rise to easy coupling with aryl fluorides and tosylates. Novel air‐ and moisture‐stable diaminophosphine oxides derived from 1,1′‐biphenyl‐2,2′‐diamine proved to be versatile preligands for the nickel‐catalyzed cross‐coupling of aryl Grignard reagents with a variety of deactivated aryl chlorides, fluorides, and tosylates (see scheme)
一次合作夫妇:章C合作双金属激活 F和C O键给人们带来方便与耦合芳氟化物和苯磺酸。事实证明,由1,1'-联苯-2,2'-二胺衍生的新型耐空气和湿气稳定的二氨基氧化膦是多用途的配体,可用于镍催化的芳基格氏试剂与各种失活的芳基氯化物,氟化物的交叉偶联。和甲苯磺酸盐(请参阅方案)。
