monophosphines has been developed and two new members of this family, 2,6‐Me2‐KITPHOS [11‐dicyclohexylphosphino‐12‐(2,6‐dimethylphenyl)‐9,10‐ethenoanthracene] and 2,6‐(MeO)2‐KITPHOS [11‐dicyclohexylphosphino‐12‐(2,6‐dimethoxyphenyl)‐9,10‐ethenoanthracene], have been prepared; palladium complexes of both are highly efficient catalysts for CC and CN bond formation with a range of electron‐rich and electron‐poor
在KITPHOS(11-二环己基膦基-12-12-苯基-9,10-乙炔蒽)单膦中通过膦炔基衍生的芳基环的邻,邻'取代可增强此类配体在钯催化的Suzuki-Miyaura交叉偶联和偶联反应中的性能布赫瓦尔德-哈特维格胺的胺,与未取代和单取代的胺相比。已经开发出KITPHOS单膦的另一种互补合成方法,该家族的两个新成员,2,6-Me 2 -KITPHOS [11-二环己基膦基-12-(2,6-二甲基苯基)-9,10-乙蒽]和2已制备6-(MeO)2 -KITPHOS [11-二环己基膦基-12-(2,6-二甲氧基苯基)-9,10-乙炔蒽];两者的钯配合物都是CC和C的高效催化剂N键与一系列富电子和贫电子的芳族氯化物以及杂芳基氯化物的形成。
