cross-coupling is a powerful C–C bond-forming transformation typically catalyzed by late transition metals. Herein, we report a mechanistic investigation into an early transition metal-catalyzed variant of this reaction. Through this mechanistic understanding, an ideal Y catalyst was determined through tuning of the metal in order to optimize the oxidation potential, which governs the rate-limiting step
烷基-烷基交叉偶联是一种强大的 C-C 键形成转化,通常由后过渡金属催化。在此,我们报告了对该反应的早期过渡金属催化变体的机理研究。通过这种机理理解,通过调整金属来确定理想的 Y 催化剂,以优化氧化电位,这决定了该反应中的限速步骤。揭示了广泛的底物范围,包括各种官能团以及活性较低的底物。
