could be used as an alternative substrate for Suzuki cross coupling. In this manuscript, a novel ppm-Pd-Fe/C catalyst has been developed by reduction of palladium acetate and iron trichloride with aqueous hydrazine in situ and supported on activated charcoal. In combined with Sphos, and metal zinc as additives, this catalyst, with 300 ppm palladium loading, could be applied in the Suzuki cross coupling
芳基三氟甲磺酸酯是一种容易获得的化合物,可用作 Suzuki 交叉偶联的替代底物。在这篇手稿中,通过用肼水溶液原位还原乙酸钯和三氯化铁并负载在活性炭上,开发了一种新型 ppm-Pd-Fe/C 催化剂。与 Sphos 和金属锌作为添加剂相结合,该催化剂的钯负载量为 300 ppm,可应用于芳基三氟甲磺酸酯与芳基新戊基乙二醇硼酸酯之间的 Suzuki 交叉偶联。
