The successful application of (DPEPhos)Ni(mesityl)Br (C1) as a pre-catalyst in the Suzuki–Miyaura cross-coupling of heteroaryl chlorides or bromides and heteroaryl boronic acids is reported. The use of C1 in this context allows for such reactions to be conducted under mild conditions (2 mol% Ni, 25 °C), including cross-couplings leading to unsymmetrical biheteroaryls. Successful transformations of this type involving problematic pyridinyl boronic acid substrates (10 mol% Ni, 60 °C) are also described.

(DPEPhos)Ni(mesityl)Br：一种空气稳定的预催化剂，用于挑战铃木-宫浦交叉偶联导致不对称的双杂芳基

报道了 (DPEPhos)Ni(mesityl)Br (C1) 作为预催化剂在杂芳基氯化物或溴化物与杂芳基硼酸的 Suzuki-Miyaura 交叉偶联中的成功应用。在这种情况下使用 C1 允许在温和条件（2 mol% Ni，25 °C）下进行此类反应，包括导致不对称二杂芳基的交叉偶联。还描述了此类涉及有问题的吡啶基硼酸底物（10 mol% Ni，60 °C）的成功转化。
