phosphite‐based catalysts for use in the CN cross‐coupling reaction. The combination of nickel tetrakis(triphenyl phosphite) Ni[P(OPh)3]4} and 1,1′‐bis(diphenylphosphino)ferrocene (dppf), and in particular a newly developed catalyst (dppf)Ni[P(OPh)3]2, were found to be extremely effective in catalyzing a range of amination reactions of anilines and amines with aryl chlorides. This new catalyst system offers
本文中,我们描述了用于CN交叉偶联反应的廉价,空气稳定的亚磷酸镍基催化剂的设计和制备。四(三亚磷酸三苯酯)镍Ni [P(OPh)3 ] 4 }和1,1'-双(二苯基膦基)二茂铁(dppf)的组合,尤其是新开发的催化剂(dppf)Ni [P(OPh) )3 ] 2,被发现在催化一系列苯胺和胺与芳基氯化物的胺化反应中极为有效。这种新的催化剂体系提供了通常用于CN键形成的双(环辛二烯基)镍[Ni(COD)2 ]和钯(0)催化剂的替代品。
