anionic complex as a key intermediate, a regio- and stereoselective multicomponent coupling reaction of perfluoroarenes, aryl Grignard reagents, and 1,3-butadiene in a 1:1:2 ratio was achieved, resulting in the formation of 1,6-octadiene derivatives containing two aryl groups, one from the perfluoroarene and the other from the aryl Grignard reagent, at the 3- and 8-positions, respectively.
分离出阴离子Ni配合物,并通过X射线晶体学确定其结构。以这种阴离子配合物为关键中间体,全氟芳烃,芳基格氏试剂和1,3-丁二烯以1:1:2的比例进行了区域和立体选择性多组分偶联反应,从而形成了1,6 -辛二烯衍生物在3和8位分别含有两个芳基,一个来自全氟芳烃,另一个来自芳基格氏试剂。
