spectroscopy (FT-IR). Various substituted phenylboronic acids were used to research the one-pot reaction. The results were highly satisfactory, not only got high yield, but reduced reaction time. Leakage experiments further demonstrated that there is no leaching of active palladium nanoparticles during the reactions. Catalysts could be reused for at least five cycles and activity is not significantly decreased
摘要 制备了含有钯纳米颗粒 (NPs) 的双功能 Cr-MOF 催化剂。结合 Pd NPs 的高活性和 MIL-101-NH2 中的碱基位点,催化剂(Pd@MIL-101-NH2)在一锅 Suzuki-Knoevenagel 反应中表现出独特的催化活性。Pd@MIL-101-NH2 已通过 X 射线衍射 (XRD)、透射电子显微镜 (TEM)、热重分析 (TGA) 和傅立叶变换红外光谱 (FT-IR) 进行表征。各种取代的苯基硼酸被用于研究一锅反应。结果非常令人满意,不仅收率高,而且反应时间缩短。泄漏实验进一步证明在反应过程中没有活性钯纳米颗粒的浸出。
