摘要

利用两种有效催化剂（如 Fe(acac)3 和 Ni(acac)2），在 C2 取代的 1-bromocyclobut-1-enes 和格氏试剂之间建立了交叉偶联反应。铁催化剂可在 THF 中使用，但需要 NMP 作为助溶剂，其优点是可以与烷基格氏试剂发生交叉偶联反应。镍催化剂无需任何添加剂即可在 THF 中促进反应，并与富电子芳基格氏试剂发生高反应性。这些催化剂以良好的收率生成了各种类型的取代环丁烯。

Earth-Abundant Metal-Catalyzed Cross-Coupling Reactions of 1-Bromocyclobut-1-enes with Grignard Reagents

Cross-coupling reactions have been developed between C2-substituted 1-bromocyclobut-1-enes and Grignard reagents using two effective catalysts, e.g., Fe(acac)₃ and Ni(acac)₂. The iron catalyst works in THF but requires NMP as the co-solvent, with the advantage of achieving cross-coupling reactions with alkyl Grignard reagents. The nickel catalyst was able to promote the reactions in THF without any additive and showed high reactivity with electron-rich aryl Grignard reagents. These catalysts gave various types of substituted cyclobutenes in good yields.
