Synthesis and characterization of the new air-stable pre-catalyst (DPEPhos)Ni(2-mesityl)Br (C1) is reported, along with the application of this pre-catalyst in the cross-coupling of secondary amines/azoles with activated (hetero)aryl chlorides to afford tertiary (hetero)anilines. The performance of C1 in these cross-couplings is competitive with some of the best and/or most widely employed nickel catalysts for such transformations.
报道了新的空气稳定的前催化剂(DPEPhos)Ni(2-二甲苯基)Br(C1)的合成和表征,以及该前催化剂在次烷胺/唑类物与活化(杂)芳基氯化物的偶联反应中的应用,从而得到三级(杂)苯胺。C1在这些偶联反应中的表现与一些最佳和/或最广泛使用的镍催化剂相竞争。
