A nickel‐catalyzed asymmetric diarylation reaction of vinylarenes enables the preparation of chiral α,α,β‐triarylated ethane scaffolds, which exist in a number of biologically active molecules. The use of reducing conditions with aryl bromides as coupling partners obviates the need for stoichiometric organometallic reagents and tolerates a broad range of functional groups. The application of an N‐oxyl
镍催化乙烯基芳烃的不对称二芳基化反应能够制备手性 α,α,β-三芳基化乙烷支架,该支架存在于许多生物活性分子中。使用芳基溴化物作为偶联伙伴的还原条件消除了对化学计量有机金属试剂的需求,并耐受广泛的官能团。将N-氧基自由基作为配体应用于镍催化剂代表了一种促进镍催化交叉偶联反应的新方法。
